    Default Dovecot 2.0.rc3: CAPABILITY response indicates no support of ACL extension

    Hi

    While trying to create an IMAP folder within the OX-Webmail I receive the following error message:

    Code:
    The composed rights could not be applied to new folder INBOX/test due to missing administer right in its initial rights specified by IMAP server. However, the folder has been created on server imap.example.com with login user1@example.com (user=4, context=3000000). (IMAP-2016, 1704769737-187)
    I'm running OX 6.17.0 Rev12 ( 2010-07-14 13:30:21 ) on Debian Lenny with Dovecot 2.0.rc3

    The groupware log files contains the following error message:
    Code:
    com.openexchange.imap.acl.ACLExtensionAutoDetector$ACLExtensionCallable call
    INFO: 
    	IMAP server [imap.example.com/xxx.xxx.xxx.xxx:143] CAPABILITY response indicates no support of ACL extension.
    However ACL support has been enabled on the dovecot side and the server also announces the ACL capability:
    Code:
    telnet imap.example.com 143
    Trying xxx.xxx.xxx.xxx...
    Connected to imap.example.com.
    Escape character is '^]'.
    * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready.
    aa login user1@example.com pass

    According to the dovecot debug output OX successfully creates and subscribes the folder, but deletes it afterwards (without unsubscribing), furthermore the GETACL and MYRIGHTS command returns administrator privileges (lrwstipekxacd) :

    I've also tried to set

    com.openexchange.imap.User2ACLImpl=Dovecot
    instead of 'auto' within /opt/open-xchange/etc/groupware/imap.properties without any luck.


    Creating folders and setting ACLs with another IMAP client (ex. thunderbird) works correctly.

    Any help is appreciated

    Thanks and regards
    Christian

    Hi Christian,

    thanks for reporting this. AFAIK Dovecot 2 is in development right now, so we don't have optimized our code for this server yet. Of course Dovecot is a very important IMAP implementation for us. Could you please report this at https://bugs.open-xchange.com/ to get it into the development cycle for future releases?

    Thanks!
    Martin
