Re: blank attribute value.

[Jeremy Hallum <jhallum@umich.edu>]

Thanks Francois, for the answer.  

I asked this question in the context that I'm trying to figure out how to 
make the OS X automounter understand the ldap schema to mount NFS disks.  
Theoretically it's possible, but I haven't sacrificed enough chickens to 
the Panther Gods to make it so. 

According to most of the websites that I've read, if you want the 
automounter to act as the intermediary, you have to have the VFSdir 
attribute blank (which maps to the mountDirectory in the apple LDAP 
schema), and add the VFSopts attribute value 'net' to the entry, and it 
SHOULD work.   It works in a netinfo entry, anyway, so I would think that 
it would work in an LDAP entry (though it doesn't). 

I figured that was the answer, but I wanted to be sure.
 
Thanks!
