There are some problems connnecting a Linux NIS client to a FreeBSD NIS server (Linux is RH9 and freeBSD is 4.9 RELEASE but i believe it concerns all versions) Description: Having both sides setup , users always get an authentication failure on the linux boxes. Same problem is described in http://lists.freebsd.org/pipermail/freebsd-net/2003-August/001126.html There it is suggested that the only problem is a missing NIS map ( named master.passwd in freeBSD) shadow.byname. However patching as suggested the /var/yp/Makefile doesnot solve the problem although it sure is necssary to make the shadow map. Linux authentication routine is distrubbed by the presence of asterisk in tha passwd tables and maps an really foolishly expects an "x" I have made small modification in line 470 changing from print $$1":*:"$$3":"$$4":"$$8":"$$9":"$$10}' $^ \ to print $$1":x"$$3":"$$4":"$$8":"$$9":"$$10}' $^ \ FreeBSD NIS clients seem not have spotted the difference. However having searched for possible implications i must point out that the asterisk is used in the /usr/src/usr.sbin/rpc.yppasswdd/yppasswdd_server.c (read comments line 348 ) so i suggest changing line 416 pw->pw_name, *(ptr+1) == '*' ? "*" : pw->pw_passwd, to pw->pw_name, *(ptr+1) == ('*'||'x') ? "x" : pw->pw_passwd, Results: Linux client users can cleanly authenticate now I have no indication of any implication in FBSD NIS clients but it sure is necessary for someone to look more thoroughly More work to be done: A user on a linux client still cant change his password using yppasswd , so .. they still have to visit a freebsd box and use yppasswd there :-) Conclusion: It would be appreciable if someone (on either side) made NIS work fine out of the box Thank you
