I'm not an expert with ldap but the error means what it says it can't connect to the server the credentials are invalid. I'd recommend double checking what you have set in the config file and you could try looking at the ldap server logs to see if they give you any other information.

Problem finally solved.
Thank you for your help.

Quote from: SKaero on Today at 01:59:45 AMI don't see anything there that should be causing an issue. In the plugins/password/password.php file can you change "Password plugin: Hash method not supported." to "Password plugin: Hash method (". $method .") not supported." and then post the error so we can see what method its trying to use?

Thanks for your help. It was my wrong and I have solved that problem. Still, I found another problem in the log file(see https://www.roundcubeforum.net/index.php?topic=31768.0). Could you help me check it?

I find the error message in the log file of Roundcube as follows. What is about? How do I solve it?

I don't see anything there that should be causing an issue. In the plugins/password/password.php file can you change "Password plugin: Hash method not supported." to "Password plugin: Hash method (". $method .") not supported." and then post the error so we can see what method its trying to use?

Would you know if I need to change anything beside my script and the autologin plugin?
Feels strange if I need to change anything in the "index.php".

I don't have any examples to point to other than the autologin plugin that ships with Roundcube. If you have a modified plugin that isn't working if you post that and the problem I could try to help debug the issue.

Is there anymore details in the nginx or php-fpm error logs, hard to point to anything without more information on why its failing.

Thank you. I had one before but that one isn't working now.
I posted the user info to a file on the roundcube and from there it logged in.
Do you have help info or links?
