Virtual domains and LDAP

[James Satterfield]

I'm using a virtual domain setup based on usernames. So I have a domain
uberduper.com and a user jsatter at uberduper.com
I've got imapd setup to use saslauthd, and saslauthd setup to auth against LDAP.
If I assign the uid of jsatter at uberduper.com in ldap, testsaslauthd can
successfully auth, but imapd cannot. Looking at the logs suggests that imapd
isn't passing the entire username jsatter at uberduper.com to saslauthd. Just
"jsatter"

Thanks,
James.
