Ok thanks for your answer.
Using this given example:
http://cvs.sourceforge.net/viewcvs.py/pam/Linux-PAM/modules/pam_permit/pam_permit.c?rev=1.4&view=markup
and keeping nobody as "username", i would just have to replace return
PAM_SUCCESS (in pam_sm_authenticate) by return PAM_IGNORE ?
("nobody" would be used as username and the next pam module would take 
care of the password check)
Sorry if the question "sounds" silly, the pam module writer guide
doesn't look straightforward to me. :)

(sorry, this is the last off-topic mail to the gdm list)
