authentication failure

[Skale, Franz]

Hi,
your ptcache.db seems to be broken.
Try the following:
1.) Create a backup ! (always!)
E.g. cp -a /var/lib/imap/ptclient/ptscache.db 
/var/lib/imap/ptclient/ptscache.db.bak
2.) Dump the file by issuing following command:
su - cyrus -c /usr/lib/cyrus-imapd/ptdump
Check all the entries and the timestamps.
3.) Clear the DB by using ptexpire: (Man Page: 
https://www.cyrusimap.org/imap/reference/manpages/systemcommands/ptexpire.html)
Issue: (Default 3h).
su - cyrus -c /usr/lib/cyrus-imapd/ptexpire
Check again by logging in as user again.
Dump again and verify the timestamp by using following command:
date -d @[timestamp]

Best regards
Franz
