Hello,

Since I have activated acl plugin, master password is no longer working.

I'm running dovecot 2.1.9 with master password and acl plugin (among 

others). I have attached my configuration. If I disable acl plugin, it works, but if I enabled it, dovecot fails. In the client, I get:

amateo@joshua:~$ telnet myotis30.um.es 143 Trying 155.54.211.169... Connected to myotis30.um.es. Escape character is '^]'.

Refer to server log for more information. [2013-02-27 11:46:50]

  and in the server I get:

This user, accesed directly, without master user, works perfectly, with 

no problem, even with acl plugin.

Any idea?
