This patch enables mod_auth_pam to create a PAM session
and to use PAM credentials for a request. This is at
least usefull if you want to handle files in the AFS
filesystem with your webserver.
The original patch was written for mod_auth-Pam for
Apache 1.3 at the TU Chemnitz. We modified it for
mod_auth_pam for Apache 2.
The PAM handle is stored for each request in a memory
pool that is allocated for this request and
automatically removed after the request is done. Each
request is handled within a seperate process group.
This behavoir can be configured per directory within
the apache configuration with the directive
AuthPAM_SetCred (on|off, default is off).
The patch can be used for the original mod_auth_pam for
Apache 2 and for the version with the PAM servicename
as a configuration option (see [ 1058140 ]
mod_auth_pam: support for specifying service-name).
I'm new to PAM, AFS and apache programming and my C is
rusty, so feedback is welcome.
