Hi All,
Sorry for the extra e-mail. Given I am helping roll out this identical 
setup again I am thinking I will test another approach which I am hoping 
will work but given having two or more PCs trying to access the 'mail' 
folder crashed at this site on the weekend, I went away from this. But 
in my thinking perhaps it 'might' work if same login ID is not used to 
access the exact same area.
Example:
1. Setup user "accounts" and open the permissions of its folders. 
(${HOME} = /u/home/accounts)
2. Create "accounts2" but have its ${HOME} directory set to the same
as
"accounts". (${HOME} = /u/home/accounts)
Make sure accounts2 can fully access everything - perhaps I will need to 
enforce a central GID (group ID) for each user to belong to (eg., accounts).
3. See if the same crash issue happens if using a different login name.
This is using the reverse approach of not having separate Root Folder 
paths for the same Linux login ID.
If this does work I can then reverse engineer the issue at the site over 
the weekend as well.
Will keep you posted.

As always, I remain at your service.
Kindest Regards,
