Sieve authentification (against mysql) problem

[Bjoern Burger]

Hello,

i have trouble with sieve and hope someone can tell me a way out.
Google is not my friend today.

I have installed a Debian server with Cyrus, Sendmail and WebCyradm.
The user authentication works against a mysql database.

Almost every thing works fine, all usernames and passwords are stored in the MYSQL, i can create 
accounts
with WebCyradm, can recieve mail and send mail.

But i can´t set vacation messages anymore.
I set them with WebCyradm.

It works fine for a while, i have tested it a lot, because I changed
a little bit in the Webcyradm php files.

I got now an error "Failed to login" , when I try to set a vacation message.
When I print the variables which used for authentication it prints cyrus with the correct password.

It seems that sieve doesn´t authenticates against the mysql Database anymore(?).
There are no entrys in the mysql.log for trying to get a password for the cyrus user from the mysql 
database.

Using the original WebCyradm files, after getting trouble, works for 1 or 2 tries, but now I get the 
same error with
the original files.

So i installed cyrus-clients on a remote machine und try sivtest.
I can connect to the server, but get an "Authentication failed. generic failure
" error after typing in my password.

I call sivtest "sivtest -u cyrus machinename.domain.tld" und get a prompt that asks for the password.

But now there are "new" messages in auth.log. And i see that cyrus/sieve try to get a username for 
root at machinename
from the mysql database.

Tried to solve this by adding root at machinename with a password to the accountuser table in the mysql 
database, but it doesn´t work.

I can´t see the wood for the trees.

hopefully
