    First I want to thank you for your site that I consult very often and that is really of great help.

    I installed a server in following The Perfect Setup - Ubuntu Feisty Fawn (Ubuntu 7.04) + ISPconfig + Roundcube. But I currently have a problem, I can't login with either POP3 or IMAP4, server responds but then rejects my password

    ##NAME: daemons:0
    # The number of daemon processes that are started. authdaemon is typically
    # installed where authentication modules are relatively expensive: such
    # as authldap, or authmysql, so it's better to have a number of them running.
    # PLEASE NOTE: Some platforms may experience a problem if there's more than
    # one daemon. Specifically, SystemV derived platforms that use TLI with
    # socket emulation. I'm suspicious of TLI's ability to handle multiple
    # processes accepting connections on the same filesystem domain socket.
    # You may need to increase daemons if as your system load increases. Symptoms
    # include sporadic authentication failures. If you start getting
    # authentication failures, increase daemons. However, the default of 5
    # SHOULD be sufficient. Bumping up daemon count is only a short-term
    # solution. The permanent solution is to add more resources: RAM, faster
    # disks, faster CPUs...


    ##NAME: authdaemonvar:2
    # authdaemonvar is here, but is not used directly by authdaemond. It's
    # used by various configuration and build scripts, so don't touch it!


    # Dump additional diagnostics to syslog
    # DEBUG_LOGIN=0 - turn off debugging
    # DEBUG_LOGIN=1 - turn on debugging
    # DEBUG_LOGIN=2 - turn on debugging + log passwords too
    # ** YES ** - DEBUG_LOGIN=2 places passwords into syslog.
    # Note that most information is sent to syslog at level 'debug', so
    # you may need to modify your /etc/syslog.conf to be able to see it.


    # A comma-separated list of option=value pairs. Each option is applied
    # to an account if the account does not have its own specific value for
    # that option. So for example, you can set
    # DEFAULTOPTIONS="disablewebmail=1,disableimap=1"
    # and then enable webmail and/or imap on individual accounts by setting
    # disablewebmail=0 and/or disableimap=0 on the account.


    # courierlogger(1) options, e.g. to set syslog facility


    # Options documented in ldap.conf(5) can be set here, prefixed with 'LDAP'.
    # Examples:

    I am able to send and receive emails using UNIX 'mail' application for example.

    I suspect something wrong with the authentication modules but I have no clue what I can try

    Thanks for any suggestions

    I tried to find a solution all the day without success, I reinstalled all the part with imap and pop in following the tuto but still get the same result. The worst of this story is that it was working a few days ago.

    Has someone a clue about what could cause (POP and IMAP failed to login), because I am able to login with the username password with shell access.

    Could this file be responsible of that

    /etc/default/saslauthd ?

    Thanks for future answers

    No, that has nothing to do with Courier. Usually Courier is working out of the box. Did you modify any of the Courier configuration files?

    Thanks Falko for the answer, at long last I succeeded to make it works.

    I remove all courier stuff

    apt-get remove courier-authdaemon courier-base courier-imap courier-imap-ssl courier-pop courier-pop-ssl courier-ssl gamin libgamin0 libglib2.0-0

    I check if some entries were still existing
    locate courier-imap

    and deleted all the entries manually, and reinstall with

    apt-get install courier-authdaemon courier-base courier-imap courier-imap-ssl courier-pop courier-pop-ssl courier-ssl gamin libgamin0 libglib2.0-0

    but some files were missing in



    so I took them from another server and after that it was still necessary to reboot the server.

    I don't know what was wrong but everything is working again.
