seems to mess up the pam for swat.
[root@host67 security]# rpm -qf /etc/pam.d/samba
samba-3.0.25b-1.el4_6.4
[root@host67 security]# cat /etc/pam.d/samba
#auth required /lib/security/pam_stack.so service=system-auth
#account required /lib/security/pam_stack.so service=system-auth
auth required pam_stack.so service=system-auth
account required pam_stack.so service=system-auth
and now it works
See below for debug/effort
