[Samba] certain users can't map home directories

Tue Mar 25 15:44:12 MDT 2014

No responses so far.  I'm really trying to find something that will give 
someone a clue.  The *only* thing I can find common to the users that 
don't work on windows 7 is their unix id is > 11000.  No idea why or 
even what to look for but it is the only common thing I can find with 
them.  Hoping this sets a light bulb off with someone or I'm going to 
have to roll back to 3.033.

Sincerely,

Doug Tucker
