I am receiving krbtgt/<hostname>@REALM

I have this working perfectly on a CentOS 5.2 system with kernel
2.6.18 using OpenLDAP 2.3.27, cyrus-sasl 2.1.22, and krb5 1.6.1
without any additional configuration.

It could certainly having something to do with Linux versus AIX or
OpenLDAP 2.3.27 versus 2.4.12 or krb5 1.6.1 versus 1.6.3.
