[imp] IMAP Connection Issue: "no auth attempts"

[Jan Schneider]

Zitat von Alexander Lasley <alasley at mail.redskylab.com>:

> After installing IMP, testing the IMAP connection via  
> /test.php?app=imp is successful; "Namespace Information" and "IMAP  
> server capabilities" are shown to me. However, connections through  
> the web interface fail. I have tried two different things:
>
> 1) Logging in to the mail account while logged in to Horde as the  
> default "Administrator" user. This fails and produces the message  
> "User Administrator is not authorized for Mail" in the logs. I  
> stopped here because this is ultimately not the way I intend to use  
> Horde/IMP anyway.
> 2) Using IMP as the application to handle authentication for Horde.  
> This fails and produces slightly more useful information in the logs.

> Web server information:
> CentOS 6.6
> nginx 1.0.15 installed via yum *
> php-fpm 5.4.37 installed via yum
> Horde 5.2.3 installed via PEAR
> IMP 6.2.7 installed via PEAR
>
> Mail server information:
> CentOS 6.6
> dovecot 2.0.9 installed via yum
>
> * I know that nginx isn't officially supported, but my issue does  
> not seem related to the web server; no relevant error messages are  
> showing up in nginx's log.

> I've replaced sensitive information in the logs with the following:
> Horde installed into the document root /path/to/horde
> Horde running on webmail.domain.tld with IP address xxx.xxx.xxx.xxx
> Dovecot/Postfix running on mail.domain.tld with IP address yyy.yyy.yyy.yyy
> Attempting to log in as username at mail.domain.tld
> My personal IP zzz.zzz.zzz.zzz
>
> Dovecot logs:
> Feb 11 06:40:46 mail dovecot: auth: Debug: Loading modules from  
> directory: /usr/lib64/dovecot/auth

1) Don't edit backends.php!
2) Enable debug logs (in backends.local.php!) and check the IMAP  
connection logs.
