Problem writing module



Hello all.
I'm currently developing a module for PAM and having some difficulties.
First, the module is linked with the NSS lib (from mozilla). Trying it on 
login, wverything runs well, pam_sm_authenticate() returns PAM_SUCCESS, and 
there comes the problem. The login locks for some time, and then, prints a 
message of time out, showing the login prompt again. I have no idea why is 
this happening. I've tried to substitude the module's code for the 
pam_permit.c code, wich gave me another error: "Login incorrect" (the 
pam_sm_authenticate wasn't called and I assume that was because the little 
code was linked to the NSS lib and something went wrong when loading the 
module)...Does anyone know this behaviour or can help me debugging?? I have 
no idea how to debug the login...

Also, I did a little program that uses this module, and, pam_authenticate() 
returns PAM_SUCCESS, and then, the shell is available again. So, nothing 
strange here. Only when using it with login.

Thanks in advance
