When you say pam_krb5 fails, is it failing for the normal login
without any samba involved, or only when a samba program is calling
pam which calls pam_krb5?

Is this the Solaris provided pam_krb5, or did you build an open source
version?

Did you replace any of the /usr/lib/krb5 libs?

It could be a problem of the samba program loading the MIT libs, and
the pam_krb5 loading /usr/lib/krb5/libkadm5clnt.so.1 and
/usr/lib/gss/mech_krb5.so.1. There have duplicate routine
names. The pam_krb5 may be calling the MIT versions of these
routines and failing.

If you can run the program under truss you can see what libs are loaded,
and maybe where the pam_krb5 is failing.
