Topic on Manual talk:Active Directory Integration

Hello, dear support!

I am trying to connect my instance of MW to our AD exactly as explained in this page, to which I am adding this topic. I spent a lot of time, reading such discussions on the subject, but cannot get it working.

Here, to save your time, I am attaching my ldap.json and LocalSettings.php (sure, with dummy data replaced sensitive information).

The symptoms:

1. I still see both username and password fields on the login page, but without the standard button "Log in", only with the LDAP log in button, which is.. strange
2. On clicking the LDAP login button I see error message: Could not authenticate credentials against domain "mydomainname.com"
3. php extensions/LDAPProvider/maintenance/ShowUserGroups.php --domain ldap.service  --username ldap.user returns only this: Full DNs:     Short names:
4. php extensions/LDAPProvider/maintenance/CheckConnection.php --config /path/to/ldap.json --domain ldap.service "(samaccountname=*)" returns tons of information, related to our LDAP server (DNs)
5. php extensions/LDAPProvider/maintenance/CheckLogin.php --domain ldap.service  --username ldap.user when then I enter correct password it said FAILD, but if I just hit Enter on the password prompt it says OK
6. php extensions/LDAPProvider/maintenance/ShowUserInfo.php --domain ldap.service  --username ldap.user returns nothing

ldapsearch returns correct output on test connection.

We restarted Apache after adding PHP modules, we did update.php after applying this new LDAP extensions, as advised in the topic.

Please, help!

Solved.

Hi, how did you solved?

Hi Arsenii Gorkin,

I'm getting the same exact error as you had. In the CheckLogin.php, if I entered my password it returns Failed. But if I just press enter, it returns OK. ShowUserInfo.php was giving correct results.

Can you please tell us on how you solve the issue on your side? Thank you very much
