# Group access and permissions
|
|
|
|
Configure your groups to control group permissions and access.
|
|
|
|
## Group push rules **(PREMIUM)**
|
|
|
|
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/34370) in GitLab 12.8.
|
|
> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/224129) in GitLab 13.4.
|
|
> - [Moved to Settings/Repository](https://gitlab.com/gitlab-org/gitlab/-/issues/220365) in GitLab 15.4.
|
|
|
|
Group push rules allow group maintainers to set
|
|
[push rules](../project/repository/push_rules.md) for newly created projects in the specific group.
|
|
|
|
In GitLab 15.4 and later, to configure push rules for a group:
|
|
|
|
1. On the left sidebar, select **Settings > Repository**.
|
|
1. Expand the **Pre-defined push rules** section.
|
|
1. Select the settings you want.
|
|
1. Select **Save Push Rules**.
|
|
|
|
In GitLab 15.3 and earlier, to configure push rules for a group:
|
|
|
|
1. On the left sidebar, select **Push rules**.
|
|
1. Select the settings you want.
|
|
1. Select **Save Push Rules**.
|
|
|
|
The group's new subgroups have push rules set for them based on either:
|
|
|
|
- The closest parent group with push rules defined.
|
|
- Push rules set at the instance level, if no parent groups have push rules defined.
|
|
|
|
## Restrict Git access protocols
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/365601) in GitLab 15.1 [with a flag](../../administration/feature_flags.md) named `group_level_git_protocol_control`. Disabled by default.
|
|
|
|
FLAG:
|
|
On self-managed GitLab, by default this feature is not available. To make it available, ask an administrator to
|
|
[enable the feature flag](../../administration/feature_flags.md) named `group_level_git_protocol_control`. On GitLab.com,
|
|
this feature is available.
|
|
|
|
You can set the permitted protocols used to access a group's repositories to either SSH, HTTPS, or both. This setting
|
|
is disabled when the [instance setting](../admin_area/settings/visibility_and_access_controls.md#configure-enabled-git-access-protocols) is
|
|
configured by an administrator.
|
|
|
|
To change the permitted Git access protocols for a group:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Settings > General**.
|
|
1. Expand the **Permissions and group features** section.
|
|
1. Choose the permitted protocols from **Enabled Git access protocols**.
|
|
1. Select **Save changes**.
|
|
|
|
## Restrict group access by IP address **(PREMIUM)**
|
|
|
|
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/1985) in GitLab 12.0.
|
|
> - [Moved](https://gitlab.com/gitlab-org/gitlab/-/issues/215410) from GitLab Ultimate to GitLab Premium in 13.1.
|
|
|
|
To ensure only people from your organization can access particular
|
|
resources, you can restrict access to groups by IP address. This group-level setting
|
|
applies to:
|
|
|
|
- The GitLab UI, including subgroups, projects, and issues.
|
|
- [In GitLab 12.3 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/12874), the API.
|
|
|
|
### Security implications
|
|
|
|
You should consider some security implications before configuring IP address restrictions.
|
|
|
|
- Administrators and group owners can access group settings from any IP address, regardless of IP restriction. However:
|
|
- Groups owners cannot access projects belonging to the group when accessing from a disallowed IP address.
|
|
- Administrators can access projects belonging to the group when accessing from a disallowed IP address.
|
|
Access to projects includes cloning code from them.
|
|
- Users can still see group and project names and hierarchies. Only the following are restricted:
|
|
- [Groups](../../api/groups.md), including all [group resources](../../api/api_resources.md#group-resources).
|
|
- [Project](../../api/projects.md), including all [project resources](../../api/api_resources.md#project-resources).
|
|
- When you register a runner, it is not bound by the IP restrictions. When the runner requests a new job or an update to
|
|
a job's state, it is also not bound by the IP restrictions. But when the running CI/CD job sends Git requests from a
|
|
restricted IP address, the IP restriction prevents code from being cloned.
|
|
- Users may still see some events from the IP restricted groups and projects on their dashboard. Activity may include
|
|
push, merge, issue, or comment events.
|
|
- IP access restrictions for Git operations via SSH are supported only on GitLab SaaS.
|
|
IP access restrictions applied to self-managed instances block SSH completely.
|
|
|
|
### Restrict group access by IP address
|
|
|
|
To restrict group access by IP address:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Settings > General**.
|
|
1. Expand the **Permissions and group features** section.
|
|
1. In the **Restrict access by IP address** field, enter IPv4 or IPv6 address ranges in CIDR notation.
|
|
1. Select **Save changes**.
|
|
|
|
In self-managed installations of GitLab 15.1 and later, you can also configure
|
|
[globally-allowed IP address ranges](../admin_area/settings/visibility_and_access_controls.md#configure-globally-allowed-ip-address-ranges)
|
|
at the group level.
|
|
|
|
## Restrict group access by domain **(PREMIUM)**
|
|
|
|
> - Support for specifying multiple email domains [added](https://gitlab.com/gitlab-org/gitlab/-/issues/33143) in GitLab 13.1.
|
|
> - Support for restricting access to projects in the group [added](https://gitlab.com/gitlab-org/gitlab/-/issues/14004) in GitLab 14.1.2.
|
|
> - Support for restricting group memberships to groups with a subset of the allowed email domains [added](https://gitlab.com/gitlab-org/gitlab/-/issues/354791) in GitLab 15.1.1
|
|
|
|
You can prevent users with email addresses in specific domains from being added to a group and its projects.
|
|
|
|
To restrict group access by domain:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Settings > General**.
|
|
1. Expand the **Permissions and group features** section.
|
|
1. In the **Restrict membership by email** field, enter the domain names.
|
|
1. Select **Save changes**.
|
|
|
|
Any time you attempt to add a new user, the user's [primary email](../profile/index.md#change-your-primary-email) is compared against this list.
|
|
Only users with a [primary email](../profile/index.md#change-your-primary-email) that matches any of the configured email domain restrictions
|
|
can be added to the group.
|
|
|
|
The most popular public email domains cannot be restricted, such as:
|
|
|
|
- `gmail.com`, `yahoo.com`, `aol.com`, `icloud.com`
|
|
- `hotmail.com`, `hotmail.co.uk`, `hotmail.fr`
|
|
- `msn.com`, `live.com`, `outlook.com`
|
|
|
|
When you share a group, both the source and target namespaces must allow the domains of the members' email addresses.
|
|
|
|
NOTE:
|
|
Removing a domain from the **Restrict membership by email** list does not remove the users with this email domain from the groups and projects under this group.
|
|
Also, if you share a group or project with another group, the target group can add more email domains to its list that are not in the list of the source group.
|
|
Hence, this feature does not ensure that the current members always conform to the **Restrict membership by email** list.
|
|
|
|
## Prevent group sharing outside the group hierarchy
|
|
|
|
You can configure a top-level group so its subgroups and projects
|
|
cannot invite other groups outside of the top-level group's hierarchy.
|
|
This option is only available for top-level groups.
|
|
|
|
For example, in the following group and project hierarchy:
|
|
|
|
- **Animals > Dogs > Dog Project**
|
|
- **Animals > Cats**
|
|
- **Plants > Trees**
|
|
|
|
If you prevent group sharing outside the hierarchy for the **Animals** group:
|
|
|
|
- **Dogs** can invite the group **Cats**.
|
|
- **Dogs** cannot invite the group **Trees**.
|
|
- **Dog Project** can invite the group **Cats**.
|
|
- **Dog Project** cannot invite the group **Trees**.
|
|
|
|
To prevent sharing outside of the group's hierarchy:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Settings > General**.
|
|
1. Expand **Permissions and group features**.
|
|
1. Select **Members cannot invite groups outside of `<group_name>` and its subgroups**.
|
|
1. Select **Save changes**.
|
|
|
|
## Prevent a project from being shared with groups
|
|
|
|
Prevent projects in a group from
|
|
[sharing a project with another group](../project/members/share_project_with_groups.md)
|
|
to enable tighter control over project access.
|
|
|
|
To prevent a project from being shared with other groups:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Settings > General**.
|
|
1. Expand the **Permissions and group features** section.
|
|
1. Select **Projects in `<group_name>` cannot be shared with other groups**.
|
|
1. Select **Save changes**.
|
|
|
|
This setting applies to all subgroups unless overridden by a group owner. Groups already
|
|
added to a project lose access when the setting is enabled.
|
|
|
|
## Prevent users from requesting access to a group
|
|
|
|
As a group owner, you can prevent non-members from requesting access to
|
|
your group.
|
|
|
|
1. On the top bar, **Main menu > Groups** and find your group.
|
|
1. Select **Your Groups**.
|
|
1. Find the group and select it.
|
|
1. From the left menu, select **Settings > General**.
|
|
1. Expand the **Permissions and group features** section.
|
|
1. Clear the **Allow users to request access** checkbox.
|
|
1. Select **Save changes**.
|
|
|
|
## Prevent project forking outside group **(PREMIUM)**
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/216987) in GitLab 13.3.
|
|
|
|
By default, projects in a group can be forked.
|
|
Optionally, on [GitLab Premium](https://about.gitlab.com/pricing/) or higher tiers,
|
|
you can prevent the projects in a group from being forked outside of the current top-level group.
|
|
|
|
This setting will be removed from the SAML setting page, and migrated to the
|
|
group settings page. In the interim period, both of these settings are taken into consideration.
|
|
If even one is set to `true`, then the group does not allow outside forks.
|
|
|
|
To prevent projects from being forked outside the group:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Settings > General**.
|
|
1. Expand the **Permissions and group features** section.
|
|
1. Check **Prevent project forking outside current group**.
|
|
1. Select **Save changes**.
|
|
|
|
Existing forks are not removed.
|
|
|
|
## Prevent members from being added to projects in a group **(PREMIUM)**
|
|
|
|
As a group owner, you can prevent any new project membership for all
|
|
projects in a group, allowing tighter control over project membership.
|
|
|
|
For example, if you want to lock the group for an [Audit Event](../../administration/audit_events.md),
|
|
you can guarantee that project membership cannot be modified during the audit.
|
|
|
|
You can still invite groups or to add members to groups, implicitly giving members access to projects in the **locked** group.
|
|
|
|
The setting does not cascade. Projects in subgroups observe the subgroup configuration, ignoring the parent group.
|
|
|
|
To prevent members from being added to projects in a group:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Settings > General**.
|
|
1. Under **Membership**, select **Users cannot be added to projects in this group**.
|
|
1. Select **Save changes**.
|
|
|
|
All users who previously had permissions can no longer add members to a group.
|
|
API requests to add a new user to a project are not possible.
|
|
|
|
## Manage group memberships via LDAP **(PREMIUM SELF)**
|
|
|
|
Group syncing allows LDAP groups to be mapped to GitLab groups. This provides more control over per-group user management. To configure group syncing, edit the `group_base` **DN** (`'OU=Global Groups,OU=GitLab INT,DC=GitLab,DC=org'`). This **OU** contains all groups that are associated with GitLab groups.
|
|
|
|
Group links can be created by using either a CN or a filter. To create these group links, go to the group's **Settings > LDAP Synchronization** page. After configuring the link, it may take more than an hour for the users to sync with the GitLab group.
|
|
|
|
For more information on the administration of LDAP and group sync, refer to the [main LDAP documentation](../../administration/auth/ldap/ldap_synchronization.md#group-sync).
|
|
|
|
NOTE:
|
|
When you add LDAP synchronization, if an LDAP user is a group member and they are not part of the LDAP group, they are removed from the group.
|
|
|
|
### Create group links via CN **(PREMIUM SELF)**
|
|
|
|
To create group links via CN:
|
|
|
|
<!-- vale gitlab.Spelling = NO -->
|
|
|
|
1. Select the **LDAP Server** for the link.
|
|
1. As the **Sync method**, select `LDAP Group cn`.
|
|
1. In the **LDAP Group cn** field, begin typing the CN of the group. There is a dropdown list with matching CNs in the configured `group_base`. Select your CN from this list.
|
|
1. In the **LDAP Access** section, select the [permission level](../permissions.md) for users synced in this group.
|
|
1. Select **Add Synchronization**.
|
|
|
|
<!-- vale gitlab.Spelling = YES -->
|
|
|
|
### Create group links via filter **(PREMIUM SELF)**
|
|
|
|
To create group links via filter:
|
|
|
|
1. Select the **LDAP Server** for the link.
|
|
1. As the **Sync method**, select `LDAP user filter`.
|
|
1. Input your filter in the **LDAP User filter** box. Follow the [documentation on user filters](../../administration/auth/ldap/index.md#set-up-ldap-user-filter).
|
|
1. In the **LDAP Access** section, select the [permission level](../permissions.md) for users synced in this group.
|
|
1. Select **Add Synchronization**.
|
|
|
|
### Override user permissions **(PREMIUM SELF)**
|
|
|
|
LDAP user permissions can be manually overridden by an administrator. To override a user's permissions:
|
|
|
|
1. On the top bar, select **Main menu > Groups** and find your group.
|
|
1. On the left sidebar, select **Group information > Members**.
|
|
1. In the row for the user you are editing, select the pencil (**{pencil}**) icon.
|
|
1. Select **Edit permissions** in the modal.
|
|
|
|
Now you can edit the user's permissions from the **Members** page.
|
|
|
|
## Troubleshooting
|
|
|
|
### Verify if access is blocked by IP restriction
|
|
|
|
If a user sees a 404 when they would normally expect access, and the problem is limited to a specific group, search the `auth.log` rails log for one or more of the following:
|
|
|
|
- `json.message`: `'Attempting to access IP restricted group'`
|
|
- `json.allowed`: `false`
|
|
|
|
In viewing the log entries, compare the `remote.ip` with the list of
|
|
[allowed IPs](#restrict-group-access-by-ip-address) for the group.
|
