8824.0. "RPC: Authentication error" by HYDRA::AXPDEVELOPER (Alpha Developer support) Thu Feb 13 1997 17:21

    I have an ISV with a strange NFS problem. The ISV has two Digital UNIX
    boxes one running V3.0 and the other V4.0. V3.0 system can NFS mount
    the disk on an IBM.  However, from V4.0 he gets:
    
    Bad MNT RPC: /ccc@ninivak: RPC: Authentication error; why = Invalid
    client credential
    
    /ccc is open to everybody to mount. Only Digital UNIX V4.0 has problem
    with it.
    
    Has anything changed on V4.0? Is it NFS2 or NFS3 problem?
    
    THank you in advance.

8824.1Something to tryNETRIX::"[email protected]"Brian HaleyFri Feb 14 1997 11:0917
Hi,

I've seen errors like this in the past when the server doesn't know who
the client is.  You might want to double-check the following:

1. The client and server can ping each other by _name_, that way you know
	the gethostbyname lookups are succeeding.  Maybe the 4.0 machine
	was just tossed onto the network and isn't in any hosts database.

2. Make sure the user on the client trying the mount is known.  If uid=1234
	tries to mount, and the server doesn't know who that is, it might be
	rejected.

Just some suggestions...

    He claims he can ping/rlogin both ways.  I forwarded your message to
    him. I'll see what he says back.
    
    Thanks.
