Authentication with PAM

Hi, we have some questions regarding informix authentication on linux using the pam-system. At the moment we have a windows nt domain with a pdc and some workstations, which authenticate themselves using the domain. Some of the workstations are informix-Clients with our software connecting to the db via odbc/informix-net, one of the workstations is our db-server. Like i said, it is also in the NT-Domain, so every login (local or via informix-net) works using user/passwd from the NT-domain (no local users on the db-server except Administrator and informix). Now we evaluate switching the DB-Server to Linux (for stability and performance reasons). We cant get rid of the other windows- workstations, because of our windows-software-clients :-) So we would like to do the db-logins using the NT-Domain. If we'd have to create every user from the NT-Domain second time on the db-server, this would be a huge drawback.. I searched google (web, comp.databases.informix,...) and found the pam_smb module, which seems to be the right choice for this purpose and installed it on the db-server (SuSE Linux 8.1 (Kernel 2.4.19-4, glibc 2.2.5), Informix 7.31UD5-1, pam_smb 1.1.6). 2 Problems : 1.) Trying pam_smb with sshd for instance, i can use my NT-Domain user/passwd only if the same user exists as a local linux-user too (even with the pam_smb-Option nolocal) 2.) It seems that our Informix-version isn't capable of using pam at all (I found some hints, but no definitive answer to that). So : Is it possible or not ? (If pam doesn't work with this Informix version at all, there is no sense in trying to solve problem 1 any longer.) Thanks and bye... Regards, Ines M'ller
