No, the client is running squeeze so 1.2.2 was the only version I used.

The server is running Solaris 10.

The [Translation] section has one entry:
Method = nsswitch

Not if I am using idmapd. If I disable it, the server gets the following
queries:
- -----
fd=31 ACCEPT from IP=[...] (IP=0.0.0.0:389)
op=0 BIND dn="" method=128
op=0 RESULT tag=97 err=0 text=
op=1 SRCH base="[...]" scope=2 deref=0
filter="(&(objectClass=posixAccount)(uidNumber=-2))"
op=1 SRCH attr=userPassword cn gidNumber uidNumber loginShell
objectClass gecos uid homeDirectory
op=1 SEARCH RESULT tag=101 err=0 nentries=0 text=
fd=32 ACCEPT from IP=[...] (IP=0.0.0.0:389)
op=0 BIND dn="" method=128

op=1 SRCH base="[...]" scope=2 deref=0
filter="(&(objectClass=posixGroup)(gidNumber=-2))"
op=1 SRCH attr=cn userPassword memberUid gidNumber uniqueMember
op=1 SEARCH RESULT tag=101 err=0 nentries=0 text=
- -----
What seems odd here is the "-2" for uid and gid. An ls on the client
shows "4294967294" for both values (it's a 64bit client).
When I enable idmapd, in /etc/default/nfs-common there are no queries
like the above.

No, I did not try that.

It is the standard kernel of squeeze (2.6.32-5-amd64) and according to
the config file this option does not exist.
