LDAP authentication is successful, but the LDAP-authenticated user cannot log in. Meanwhile, it can log in if flood attempts block the account.

Hi @htakamur,

Did you upgrade Drupal or the LDAP module? What was the last version that worked?

Thank you. I just used "composer update" without enough caution, so I was unsure which update caused the problem. I checked various combinations of core and the LDAP module and found those are not problems.

It turns out that another login-related module, i.e., "Mail Login," which enables email address login, was the reason. By removing the mail_login module, the login problem mentioned above disappears. If mail_login is installed again, the login problem emerges again. FYI, another email login module, "Email Registration," seems OK with the simultaneous use of LDAP.

I should have checked this before submitting this issue. Sorry for bothering you.

The problem stated in this ticket is happening to me, anyone can help?

Also, there were times admin/config/people/ldap/server page,
In server reachable column, status is "Binding issues, please see log."
sometimes its "Server available"

I am really unsure about this irregularity.

I even played around refreshing the page couple of times, sometimes its connected, sometimes its not.

Also facing the issue.

Oh, htakamur you were right about mail_login ! (didn't carefully read...)
Thanks !

Hello,

We are also experiencing status is "Binding issues, please see log." and then
sometimes its "Server available"

Our users are sometimes able to login and sometimes they are not able to login.

Nothing has changed in our LDAP Server and we haven't had any Drupal Code changes. Problem just started happening randomly.

Thanks in advance for any help!
