Troubleshooting NFS Services
Common Problems with NIS+
Chapter 8324
Use nismatch(1) to find the credentials for the user or host in the
cred table. If both a Local and a DES credential exist, the credentials
are for a non-root user. If only a DES credential exists, the credential
is for a root user. If necessary, change the host name. (It is easier to
change a host name than to change a user name.) You can set up an
alias to map the host’s old name to the new name.
NOTE When you are running nisaddcred or nisclient, if you see a
Changing Key message instead of a Adding Key message, you have a
duplicate user or host name in your domain.
