Ldap users get Invalid Credentials error

Gitlab version 8.13.3-ce

This is configured on a latest Docker image from gitlab (gitlab/gitlab-ce:8.13.3-ce.0)

I configured LDAP under /etc/gitlab/gitlab.rb

---

main: # 'main' is the GitLab 'provider ID' of this LDAP server label: 'LDAP' host: 'abc.test.net' port: '389' uid: 'uid' method: 'plain' # "tls" or "ssl" or "plain" bind_dn: 'user' password: 'password' active_directory: false allow_username_or_email_login: false block_auto_created_users: false base: 'DC=test,DC=net' user_filter: ''

---

I get below result when i execute #gitlab-rake gitlab:ldap:check Checking LDAP ...

LDAP users with access to your GitLab server (only showing the first 100 results) Server: ldapmain DN: cn=test1@test.net,cn=Users,cn=Global,cn=Zones,ou=UNIX,ou=Services,dc=test,dc=net uid: test1 DN: cn=test2@test.net,cn=Users,cn=Global,cn=Zones,ou=UNIX,ou=Services,dc=test,dc=net uid: test2 DN: cn=test3@test.net,cn=Users,cn=Global,cn=Zones,ou=UNIX,ou=Services,dc=test,dc=net uid: test3 DN: cn=test4@test.net,cn=Users,cn=Global,cn=Zones,ou=UNIX,ou=Services,dc=test,dc=net uid: test4

However the ldap users are unable to login to gitlab, they get invalid credentials error

I find below message in unicorn_stdout.log

ldapsearch with all the variables configured in gitlab.rb file gives me a valid result

Appreciate any help to fix this issue
