New installed Solaris 10 fails to start rusers, rquota

I installed a new Solaris 10 U8 ( 10/09 ) on a x86 Server.

The SMF-Framework set the rusers-Service into maintenance mode.

The log-File contained the following message:

Property 'name' of instance svc:/network/rpc/rusers:default is missing, inconsistent or invalid

I had to just take the data for rpc from the local file and not via nis or
anything else.

-> Modified /etc/nsswitch.conf  and the service was online.

This link was helpful in my case.
