Hello all, it's my first post on gitab :) Im working with the followings systems : - Red Hat Enterprise Linux Server release 7.1 (Maipo) - GITLAB version : gitlab-ce-7.13.5-ce.0.el7.x86_64.rpm Ive read the issues gitlab-ce#655 gitlab-ce#615 gitlab-ce#639 bit it did not yield anything... First of all, i don't understand why Ive got several Gitlab files in : - /etc/gitlab (in gitlab.rb => all is commented) - /opt/gitlab <= it'a normal place for gitlab ? - /var/opt/gitlab Which config file I have to use ? `/etc/gitlab/gitlab.rb` or `/var/opt/gitlab/gitlab-rails/etc/gitlab.yml` ?? I suppose the second one but seeing that Ive got some problems, Ive some doubts :) Secondly, I think I have well-set `/var/opt/gitlab/gitlab-rails/etc/gitlab.yml` but from the docs, if I do some modifications, I should do a **gitlab-ctl reconfigure** ?? but if I do that, my **gitlab.yml** is reseted, is it normal ? And thridly, Ive got this message when I attempt to connect to the AD server from my Gitlab : `Could not authorize you from LDAP because "Invalid credentials"` If I do a `gitlab-rake gitlab:ldap:check RAILS_ENV=production`, it yields lot of resultat (till 100 I think) ```shell Checking LDAP ... LDAP users with access to your GitLab server (only showing the first 100 results) Server: ldapmain DN: CN=artifactory,OU=Comptes de service,OU=Administration,DC=<my_company_name>,DC=fr sAMAccountName: artifactory [ lines ... ] DN: CN=svc_exchange,OU=Comptes de service,OU=Administration,DC=<my_company_name>,DC=fr sAMAccountName: svc_exchange Checking LDAP ... Finished ``` So far, everything is ""ok"" but if I do a "gitlab-ctl tail" it yields that : ```shell I, [2015-08-25T12:55:36.726054 #27391] INFO -- omniauth: (ldapmain) Callback phase initiated. E, [2015-08-25T12:55:36.727195 #27391] ERROR -- omniauth: (ldapmain) Authentication failure! missing_credentials encountered. ``` Idem from the UI. Otherwise, may I bring a credential from the AD server ? The AD admin has given to me a .pdx file (I asked him) and Ive extracted from there the private key that Ive passed into `/opt/gitlab/embedded/ssl/certs/<servername>.pem` but it yields me a new error : ```shell I, [2015-08-25T13:47:35.965352 #28600] INFO -- omniauth: (ldapmain) Callback phase initiated. E, [2015-08-25T13:47:35.971833 #28600] ERROR -- omniauth: (ldapmain) Authentication failure! ldap_error: Errno::ECONNRESET, Connection reset by peer @ io_fillbuf - fd:17 ``` Could you guide me on the right way please :D I begin to dispair ;(
