Q: nfsd: Unable to seteuid(-2)

[Claudius Schnörr]

Hello again,

after changing my clswork.map to
#       remote  local
uid     1010    1000            #nfsd -> user
uid     1000    1000            #user -> user
gid     1000    1000            #group bv -> group bv

a mount works, but the files still get the wrong uid:

drwxrwxrwx   37 4294967294 bv       0 2006-02-16 17:24 mnt/

The log of mountd seems ok.
The log of nfsd shows

nfsd[252] 02/16/106 18:51 auth_clnt.c 307 : Unable to setegid(-2): 
Invalid argument
nfsd[252] 02/16/106 18:51 auth_clnt.c 332 : Unable to setgroups: Invalid

argument
nfsd[252] 02/16/106 18:52 auth_clnt.c 352 : Unable to seteuid(1000): 
Invalid argument

And portmapd issues no log entries at all.
The mount takes about 10 seconds to be accomplished.

How can I get the mounted file system to appear with the correct uid of 
the user on the client side?
How can I prevent that delay when mounting the remote file system?
