# LDAP Rake tasks **(CORE ONLY)**

The following are LDAP-related Rake tasks.

## Check

The LDAP check Rake task will test the `bind_dn` and `password` credentials
(if configured) and will list a sample of LDAP users. This task is also
executed as part of the `gitlab:check` task, but can run independently
using the command below.

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:ldap:check
```

**Source Installation**

```shell
sudo -u git -H bundle exec rake gitlab:ldap:check RAILS_ENV=production
```

By default, the task will return a sample of 100 LDAP users. Change this
limit by passing a number to the check task:

```shell
rake gitlab:ldap:check[50]
```

## Run a group sync **(STARTER ONLY)**

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/14735) in [GitLab Starter](https://about.gitlab.com/pricing/) 12.2.

The following task will run a [group sync](../auth/ldap/index.md#group-sync) immediately. This is valuable
when you'd like to update all configured group memberships against LDAP without
waiting for the next scheduled group sync to be run.

NOTE:
If you'd like to change the frequency at which a group sync is performed,
[adjust the cron schedule](../auth/ldap/index.md#adjusting-ldap-group-sync-schedule)
instead.

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:ldap:group_sync
```

**Source Installation**

```shell
bundle exec rake gitlab:ldap:group_sync
```

## Rename a provider

If you change the LDAP server ID in `gitlab.yml` or `gitlab.rb` you will need
to update all user identities or users will be unable to sign in. Input the
old and new provider and this task will update all matching identities in the
database.

`old_provider` and `new_provider` are derived from the prefix `ldap` plus the
LDAP server ID from the configuration file. For example, in `gitlab.yml` or
`gitlab.rb` you may see LDAP configuration like this:

```yaml
main:
  label: 'LDAP'
  host: '_your_ldap_server'
  port: 389
  uid: 'sAMAccountName'
  ...
```

`main` is the LDAP server ID. Together, the unique provider is `ldapmain`.

> **Warning**: If you input an incorrect new provider users will be unable
to sign in. If this happens, run the task again with the incorrect provider
as the `old_provider` and the correct provider as the `new_provider`.

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:ldap:rename_provider[old_provider,new_provider]
```

**Source Installation**

```shell
bundle exec rake gitlab:ldap:rename_provider[old_provider,new_provider] RAILS_ENV=production
```

### Example

Consider beginning with the default server ID `main` (full provider `ldapmain`).
If we change `main` to `mycompany`, the `new_provider` is `ldapmycompany`.
To rename all user identities run the following command:

```shell
sudo gitlab-rake gitlab:ldap:rename_provider[ldapmain,ldapmycompany]
```

Example output:

```plaintext
100 users with provider 'ldapmain' will be updated to 'ldapmycompany'.
If the new provider is incorrect, users will be unable to sign in.
Do you want to continue (yes/no)? yes

User identities were successfully updated
```

### Other options

If you do not specify an `old_provider` and `new_provider` you will be prompted
for them:

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:ldap:rename_provider
```

**Source Installation**

```shell
bundle exec rake gitlab:ldap:rename_provider RAILS_ENV=production
```

**Example output:**

```plaintext
What is the old provider? Ex. 'ldapmain': ldapmain
What is the new provider? Ex. 'ldapcustom': ldapmycompany
```

This tasks also accepts the `force` environment variable which will skip the
confirmation dialog:

```shell
sudo gitlab-rake gitlab:ldap:rename_provider[old_provider,new_provider] force=yes
```

## Secrets

GitLab can use [LDAP configuration secrets](../auth/ldap/index.md#using-encrypted-credentials) to read from an encrypted file. The following Rake tasks are provided for updating the contents of the encrypted file.

### Show secret

Show the contents of the current LDAP secrets.

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:ldap:secret:show
```

**Source Installation**

```shell
bundle exec rake gitlab:ldap:secret:show RAILS_ENV=production
```

**Example output:**

```plaintext
main:
  password: '123'
  user_bn: 'gitlab-adm'
```

### Edit secret

Opens the secret contents in your editor, and writes the resulting content to the encrypted secret file when you exit.

**Omnibus Installation**

```shell
sudo gitlab-rake gitlab:ldap:secret:edit EDITOR=vim
```

**Source Installation**

```shell
bundle exec rake gitlab:ldap:secret:edit RAILS_ENV=production EDITOR=vim
```

### Write raw secret

Write new secret content by providing it on STDIN.

**Omnibus Installation**

```shell
echo -e "main:\n  password: '123'" | sudo gitlab-rake gitlab:ldap:secret:write
```

**Source Installation**

```shell
echo -e "main:\n  password: '123'" | bundle exec rake gitlab:ldap:secret:write RAILS_ENV=production
```

### Secrets examples

**Editor example**

The write task can be used in cases where the edit command does not work with your editor:

```shell
# Write the existing secret to a plaintext file
sudo gitlab-rake gitlab:ldap:secret:show > ldap.yaml
# Edit the ldap file in your editor
...
# Re-encrypt the file
cat ldap.yaml | sudo gitlab-rake gitlab:ldap:secret:write
# Remove the plaintext file
rm ldap.yaml
```

**KMS integration example**

It can also be used as a receiving application for content encrypted with a KMS:

```shell
gcloud kms decrypt --key my-key --keyring my-test-kms --plaintext-file=- --ciphertext-file=my-file --location=us-west1 | sudo gitlab-rake gitlab:ldap:secret:write
```

**gcloud secret integration example**

It can also be used as a receiving application for secrets out of gcloud:

```shell
gcloud secrets versions access latest --secret="my-test-secret" > $1 | sudo gitlab-rake gitlab:ldap:secret:write
```
