NFSv4 and pam_mount - mounting user home directories (with security?)

Ok, that problem has been solved ;)
In nfs_precmd it checks if the option in rc.conf is set. If yes, it tries to set the sysctl flag, it it fails, loads nfsd module and 
then sets again the sysctl flag.

But I have another question - maybe you will know the answer.

So I would like NFSv4 to serve user home directories across the network for all workstations, but I would like it to protect using 
user password

Eg. on workstation I want to do:

sudo mount -t nfs -o nfsv4 nfs4-server:/home/user1 /home/user1
and then I want to be asked for password of user1 at server (or in the whole network - users and passwords are stored in LDAP server 
and workstation and server have access to it)

Is it possible to do with NFSv4?
