Title: IMAP ERROR on roundcube login screen
Post by: deepakknair85 on December 26, 2012, 01:41:49 AM

Hi.

One of my client have installed Roundcube Webmail system to their panel as a mail module. It was working properly, but recently I am getting an error like this IMAP Error: Authentication for xxxx.xxx.xxx@xxxx.xxx.xxx failed (LOGIN): "a001 NO Login failed: authentication failure". I searched a lot on this issue, but couldn't find any fix.

Can anybody please help me on this? The system was setup by my client and I am web developer, I am not much aware about the admin settings of this webmail and how he configured this? If you have any idea about this issue, please help me.

Thanks All

If nothing has changed in the RoundCube configuration something changed with the mail server. Try changing the $rcmail_config['imap_auth_type'] in <RC root>/config/main.inc.php.

Hi Skaero,

I checked the main.inc.php file, the imap_auth_type is set as "NULL".

Ok, enable imap_debug in the main.inc.php and post the log of an attempted login.

The IMAP server doesn't say what authentication types it allows and since $rcmail_config['imap_auth_type'] is set to NULL is is trying to use login authentication which has most likely been disabled. Try changing $rcmail_config['imap_auth_type'] to 'DIGEST-MD5' and then 'CRAM-MD5' to see if one of those work.

Please correct /etc/dovecot/dovecot.conf,  leave only "plain" method

Code: [Select]

auth default {
  mechanisms = plain
