courier-authlib-mysql not working

[countzerocrc]

Hi,

i´m trying to set up virtual domains with postfix etc. (on Ubuntu 8.04)
But i have a problem with getting courier-authlib-mysql running.

Packages courier-authlib and courier-authlib-mysql are installed (from sources) but whenever i try to auth via imap i get the following error in my syslog:

Mar 22 15:22:25 my-servername authdaemond.plain: Unknown module 'authmysql' skipped

snip authdaemonrc

authmodulelist="authmysql authpam"

when i remove authpam here no process is spawned.

any ideas? tried removing all courier packages and reinstalling but no change.

authdaemonrc

authmodulelist="authmysql authpam"

authmodulelistorig="authcustom authcram authuserdb authldap authpgsql authmysql authpam"

daemons=5

version=""

authdaemonvar=/var/run/courier/authdaemon

DEBUG_LOGIN=2

tried setting version = authdaemond.mysql results in:
Mar 22 15:38:20 my-servername authdaemond.mysql: exec: No such file or directory

checked the lib directory:

ls /usr/lib/courier/authlib/ -la
total 63
drwxr-xr-x 2 root root  1024 Mar 15 10:34 .
drwxr-xr-x 6 root root  1024 Mar 22 15:19 ..
-rwxr-xr-x 1 root root 15228 Jun  8  2006 authdaemon
-rwxr-xr-x 1 root root   520 Jun  8  2006 authdaemond
-rwxr-xr-x 1 root root 43816 Jun  8  2006 authdaemond.plain

seems like the authdaemond.mysql file is missing. (/me not sure here )

any help would be highly appreciated
