Drobo FS Mounting and Scripts Issue

Has any one used scripts with the FS ? I have written a script and it works up to the point of one of the shares has a different user name. It ask for the name and PW and doesn’t mount the share at all.
Another issue I am having is I create a share and remove the “Everyone” from the share users and add the user that will access the share. When mounting the share it never ask for a user name or password.

I am in a domain and I use A.D. as well, also can I use Symantec Backup Exec to backup the drobo FS?
