[ldaamandy]

hi  :

i just install dovecot-2 and start ok  but login failed  for test-user . i turn 
on all debug options  , the debug info follow:

 

"Mar 25 14:40:10 cs2c dovecot: imap-login: Disconnected (auth failed, 1 
attempts): user=<q...@t.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, 
secured"

 

 and  the info of input->w_buffer is : cp01 CAPABILITY a001 LOGIN "q...@t.com" 
"q1q1q1q1"

 

 the auth of dovecot.conf:

>>>>>>>>>>>>>>>>>>>>>

passdb {
  args = /etc/dovecot.master
  driver = passwd-file
  master = yes
  pass = yes
}
passdb {
  args = /etc/dovecot-memcached.conf
  driver = dict
} 

 

userdb {
  args = /etc/dovecot-memcached.conf
  driver = dict
}
