Full information about LDAP infrastructure and users and groups can be found here:

   ...: _LDAP_GROUP_SEARCH_BASE = "ou=ip-spotlight,ou=xxx,ou=xxx,dc=xxx,dc=xxx"

In [11]: part = "gitlab"

In [12]: conn.search('cn={},{}'.format(part,_LDAP_GROUP_SEARCH_BASE), '(objectclass=*)', attributes=['*'])
Out[12]: True

In [13]: conn.entries
Out[13]: 
[DN: cn=gitlab,ou=ip-spotlight,ou=xxx,ou=xxx,dc=xxx,dc=xxx - STATUS: Read - READ TIME: 2018-05-24T16:07:15.687797
     cn: gitlab
     description: gitlab
     gidNumber: 9999
     member: uid=nskalis,ou=people,dc=xxx,dc=xxx
     objectClass: top
                  aaa
                  bbb
                  posixGroup
                  groupOfNames
     uimEntryOwner: cn=xxx,ou=xxx,dc=xxx,dc=xxx
     uimSecurityOwner: cn=xxx,ou=xxx,dc=xxx,dc=xxx]

And the related LDAP config in gitlab.rb is:

  main: # 'main' is the GitLab 'provider ID' of this LDAP server
    label: 'UIM'
    host: 'x.x.x.x'
    port: 636
    uid: 'sAMAccountName'
    bind_dn: 'uid=IP-spotlight,ou=xxx,dc=xxx,dc=xxx'
    password: 'xxx'
    encryption: 'simple_tls' 
    verify_certificates: false
    active_directory: false
    allow_username_or_email_login: false
    lowercase_usernames: false
    block_auto_created_users: true
    base: 'ou=people,dc=xxx,dc=xxx'
    user_filter: '(memberOf=cn=gitlab,ou=ip-spotlight,ou=xxx,ou=xxx,dc=xxx,dc=xxx)'
    ## EE only
    group_base: 'ou=ip-spotlight,ou=xxx,ou=xxx,dc=xxx,dc=xxx'
#     admin_group: 'cn=gitlab,ou=ip-spotlight,ou=xxx,ou=xxx,dc=xxx,dc=xxx'
    sync_ssh_keys: false

The issue is that the gitlab LDAP group stores user DN’s (of members) in an attribute called member. So I need to find a way to configure lookups as such.
The uid match for the people tree looks fine.

When I am checking the LDAP group gitlab based on my gitlab config I get no members, while I should get myself nskalis

# gitlab-rake gitlab:ldap:check
Checking LDAP ...

Server: ldapmain
not verifying SSL hostname of LDAPS server '172.31.133.12:636'
LDAP authentication... Success
LDAP users with access to your GitLab server (only showing the first 100 results)

Checking LDAP ... Finished

Could you please advise how I can map my username (nskalis) to the ldap group gitlab?
