Hi, The X/Open Single Sign-on Service (XSSO) documentation says about the return value of pam_getenvlist(): "If no values are set, a NULL pointer is returned." Linux-PAM does not return a NULL pointer, but a pointer to a NULL pointer. OpenPAM, which claims to be conform to this standard also returns a pointer to a NULL pointer if not values are set. After reading the manual pages of other OS I think XSSO should be adjusted, not our pam_getenvlist() implementation. Does somebody know more about this? Other opinions?
