cyrus after changing uid and mail address login not working any more

Hi all,

on one account we have the problem that user can't authenticate against
cyrus anymore after name and email-adress of the account was changed.

If changing a user name in kolab webadmin - the email-adress and uid is
changed also - depending on recipient policy.

One user can't login anymore with this new email-address.

In mail.log:

imap0 imap[7496]: badlogin: [2a01:4f8:0:0:0:0:0:0] unknown
AUTHENTICATE+PLAIN+TLS [SASL(-13): authentication failure: Password
verification failed]

Password is right and

testsaslauthd -u [email protected] -p

gives a positive result. Also login in kolab-webadmin works.

I tried to reproduce this with an test user. Creating a user, renaming
it, Everything works fine.

I already deleted ptscache.db and restartet kolab-server, cyrus-imapd
and kolab-saslauthd.

My pykolab / kolab-saslauthd versions:

0.8.15-0~kolab1

Any Idea?

There was once a similar question on kolab-hub

(https://www.google.com/search?q=SASL+Password+verification+failed+kolab+cyrus&ie=utf-8&oe=utf-8&client=firefox-b-e)

but now the site is rewritten to the kolb user mailinglist.

Best regards
Jan
