There is a bug with the C2 security under
4.1 (and I understand 4.1.1) that doesn't let anyone change their passwords.
There are two problems:-
1/rpc.yppasswdd dumps core
2/ ignores its second arguement
THe Sun patches to fix the first problem have as yet not fixed the problem
(I have various calls logged with the UK hotline about this).
I was running a mixed environment with my YP master running 4.0.3 succesfully
but I wanted to move everything to 4.1. To get round the problem I used
a fix which appeared on Sun-Managers which I have altered slightly. It does
as a stop gap but a correct fix is still needed from Sun.
I will happily supply more info if needed.
The second problem is easily fixed by adding another flag to the
/usr/etc/rpc.yppasswdd line in /etc/rc.local e.g.
/usr/etc/rpc.yppasswdd /var/yp/passwd -nosingle -m passwd DIR=/var/yp
This second problem applies to "NORMAL" operation as well as "C2" operation.
