FAQ
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
