Users are displayed as incorrect users, or have
access to files they should not, or both.
Is the user correctly mapped? Go into the SFU MMC, User Name Mapping
section, and check the advanced maps. If the user is mapped to an incorrect
entry, change the name to the correct entry.
Is simple mapping on? Check in the SFU MMC, User Name Mapping section,
and see if "simple mapping" is checked. If so, enable the "display simple
maps" check box, and look in the user mappings control list. See if the user is
mapping to an incorrect entry. If so, implicit mapping is the problem, because
the username matches spelling to an incorrect user. Change the name on the
UNIX side, or turn off simple mappings, which requires all users to be
explicitly mapped.
"RPC: procedure call failed" error occurs when
a "showmount" or other command is executed.
Is the NFS service running? Check the event log for the message stating that
the NFS service has started. If not, this is the cause of the problem. Wait for
the machine to finish powering up. If the event log entry is present, check the
service display in the MMC. If the service is not running, this is the cause of
the problem.
When mounting a share on a client machine as
root, permission denied errors are displayed, or
new files are listed as "nobody."
Does the share have "root" permissions enabled for that client? Check the
share permissions. An entry for "root" permissions has to exist for that specific
client listed in the permissions. If not, the "root" user is always squashed to
"nobody," although the group may still map to "root." This omission affects a
user's permissions and access.
