We use samba 2.2.9 with winbind. We use winbind for authentication. I was able to selectively limit pop3 use among winbind users on redhat 9 with this pam configuration. (As you would use it in ftpusers, in the reverse sense.) auth required /lib/security/pam_listfile.so item=user onerr=fail sense=allow file=/etc/pop3users This is the best solution for my situation, and I want to have that on my Solaris servers as well. However, I couldn't find from my long searches whether there's an equivalent of pam_listfile.so for solaris. I understand users can make their own pam modules, but I am looking for a ready made solution. I'd appreciate any help. Regards, Ben Kim
