I gave up on the mod_auth_sys. I finally got the config and the and compile to work without error, but the module was never added. Anyway, I decided to try mod_auth_pam. After some frustration getting it to build and compile, it finally cooperated and I installed it. However, something went wrong. When I try to restart httpd, I get this error: syntax error on line 261 of .../httpd.conf: Cannot load .../mod_auth_pam.so into server: .../mod_auth_pam.so: undefined symbol: pam_end the ... in the error are substituted for the full paths, just didn't want to type them completely. Line 261 of my httpd.conf reads: LoadModule pam_module modules/mod_auth_pam.so It looks just like the lines above it that were successfully loaded, so I'm not quite sure of the 'syntax error'. Any thoughts? regards, shane.
