* src/newusers.c: The user's ID must be found before the group ID to mimic useradd's behavior choices of UID and GID. * src/newusers.c: Reuse the generic find_new_uid() and find_new_gid() functions. This permits to respect the UID_MIN/UID_MAX and GID_MIN/GID_MAX variables, should * src/newusers.c: Check if the user or group exist using the external databases (with the libc getpwnam/getgrnam functions). Refuse to update an user which exist in an external database but does not exist in the local database. * src/newusers.c: Check the usernames and groupnames with check_user_name() and check_group_name() * src/newusers.c: Use isdigit() for readability. * src/newusers.c: Check if numerical IDs are valid (no remaining chars). * NEWS, src/newusers.c: Fix the support for the NONE crypt method. * src/newusers.c: Fix shadow group support (the list of admins was not defined; it is now set to an empty list).
