Re: informix + pam on linux

Hi, sorry for late reply ... :-( Following is an example about how to do a basic setup. It's a cut&paste from an internal www-page that I once created on this topic. I hope it is readable and understandable anyway: -------------------------------------------------------------- OS Setup for PAM PAMs typically reside as shared libs in /usr/lib/security. The configuration for each PAM is in /etc/pam.conf. On Linux however, if directory /etc/pam.d exists, then each module has its own configuration file in this directory and /etc/pam.conf is ignored. The following example illustrates a possible configuration for a single PAM: The service name of the PAM is "pam_chal" and the shared library implementing it is /usr/lib/security/pam_chal.so. The configuration for this PAM service consists of the following two lines: pam_chal <TAB> auth required <TAB> /usr/lib/security/pam_chal.so pam_chal <TAB> account required <TAB> /usr/lib/security/pam_chal.so where <TAB> denotes a tab character. This may be necessary, since it could be possible that the middle parameter in the line consists of only one token, which might confuse the parser when reading the configuration. These two lines are in /etc/pam.conf. On Linux, if the directory /etc/pam.d exists, they should be placed in file /etc/pam.d/pam_chal. IDS Setup for PAM To make a specific IDS server name PAM-enabled, a new set of additional parameters is used in the sqlhosts file for this server name. The parameters are: s=4,pam_serv=(...),pamauth=(...) Example 1: mfu1_pam ontlitcp onbarfix s=4,pam_serv=(pam_chal),pamauth=(challenge) This line in the sqlhosts file will setup the server name mfu1_pam to use the PAM with the service name pam_chal. The authentication mode for this server name will be challenge, so clients connecting to this servername must be prepared to handle a PAM challenge. Example 2: mfu1_pam ontlitcp onbarfix s=4,pam_serv=(other),pamauth=(password) This line in the sqlhosts file will setup the server name mfu1_pam to use the PAM with the service name other which usually is implemented by the system provided PAM module pam_unix.so. The authentication mode for this server name will be password, so clients connecting to this servername must be prepared to provide the password with the connection request. Implicit connections will be rejected. -------------------------------------------------------------- Regards, Martin -- Martin Fuerderer IBM Informix Development Munich, Germany Information Management "Thomas" <tomwic@op.pl> Sent by: owner-informix-list@iiug.org 16.03.2005 13:07 Please respond to "Thomas" To informix-list@iiug.org cc Subject informix + pam on linux Hi, can somebody tell me how to configure pam.d directory/file on Linux for IDS 9.4/10.0? Which name of file for informix will be right? ... and how this file and sqlhosts should look like? Regards, Thomas sending to informix-list
