Support for TCP in Solaris Kerberos was introduced in Solaris 10.

There are no Solaris 8 packages to provide Kerberos over TCP at this
point.  If you have a customer service agreement you can make a request
through your Sun service rep. for TCP/Kerberos support in Solaris 8.
There is no guarantee that Sun will do this as there are costs to doing
this and this support is available in Solaris 10.  In fact Solaris 10
has a number of Kerberos improvements that make interop with a MS AD
easier.
