How to set realm: cyrus-imap -> saslauthd?

[vladimir.elisseev at gmail.com]

Hello,

I'm getting troubles with imap -> saslauthd authentication,  
particularly with passing realm to saslauthd.
Both "testsaslauthd -u test -p ***" and "testsaslauthd -u test -p ***  
-r TEST.LOCAL" work fine, but "imtest -u test -a test -m PLAIN" fails  
while saslauthd prints:
do_auth : auth failure: [user=test] [service=imap] [realm=test.local]  
[mech=kerberos5] [reason=saslauthd internal error].
The problem is clear: realm should be TEST.LOCAL.
I tried to set this realm with -r switch, but saslauthd uses always  
the same whatever I set with -r. Don't have any clue, how to deal with  
this issue and how to set realm for cyrus-imap.

Regards,
Vladimir.
