Re: debugging pam modules



thanks for the reply.

that's what i made until now. but what i tried (without success) was
attach the process to gdb and try to follow it. for example starting xdm
in gdb and locating the problem in pam (without using the logs on
stderr) and backtracing it. that means it's impossible debug it with gdb
since user changes new process executions are made.

regards,
m96.
