* setup_uid_gid() split in two functions for PAM support -
* pam_setcred() needs to be called after initgroups(), but
* before setuid().
* setup_groups - set the group credentials
* set the group ID to the value from the password file entry
* set the supplementary group IDs
*
* In case of PAM enabled configurations, this shall be called before
* pam_setcred.
*
* Returns 0 on success, or -1 on failure.
