I just create a GitLab CE 11.8.0 install and configured LDAP authentication with AD. Here is the snippet of the LDAP configuration. Everything appears to be working and I can log in using AD credentials, however the admin_group configuration does not appear to be working. User that belongs to the “GitLab Admin” group are logged in as regular users instead. I do not see any errors in the logs so I am not clear on what it’s not liking.
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = YAML.load <<-'EOS'
main:
label: 'Domain AD'
host: 'dc1.domain.com"
port: 636
uid: 'sAMAccountName'
encryption: 'simple_tls'
verify_certificates: false
bind_dn: 'ldap_user@domain.com'
password: 'Password1'
active_directory: true
base: 'CN=Users,DC=domain,DC=com'
group_base: 'OU=GitLab Access,OU=Custom Security Groups,DC=domain,DC=com'
admin_group: 'GitLab Admin'
