[Web-cyradm] Problem web-cyradm : Database error

[Lindolfo Rodrigues]

    Hi people,

    I have a problem with web-cyradm, when I access my browser and try
to log with:
    user:admin
    passwd:test
    
I receive an error called "Database error" but nothing else.
I've checked the log file and no problem is listed.

ps : all daemons are started
ps1 : I can connect to telnet at 127.0.0.1 143, and he shows me the
imap banner.

what's going on?
Someone can help me?

Lindolfo Rodrigues.
