user and realm splitting in cyrus/ldap

[Marten Lehmann]

Hello,

I'm using Cyrus with saslauthd using ldap. When I am testing the setup 
with testsaslauthd it works fine. But when I am authenticating through 
cyrus (imap login) then I notice in the saslauthd logs, that cyrus seems 
to split the credentials. I'm using virtual domains, so a login looks 
like test at test.com. Through cyrus saslauthd receives

[user=test] [service=imap] [realm=test.com] [mech=ldap]

but with testsaslauthd it receives

[user=test at test.com] [service=imap] [realm=] [mech=ldap]

as I expected it. How can I tell cyrus not to split it up to realms?

Regards
Marten
