Because I found this moderately interesting I decided to do a little more... this is as close to silver platter as it gets...

Code:
 

break on

$=setoption("WrapAtEOL","ON")

;**************************

;Get the user's groups

;**************************

$cn="cn=" + @fullname

$ou="ou=user,ou=xyz"

$dc="dc=your,dc=domain,dc=com"

$objUser = GetObject("LDAP://" + $cn + "," + $ou + "," + $dc)

$Groups = $objUser.Getex("memberof")

;***********************************

;Find the Groups with LOC and get the description

;only displaying the 2nd part by using the delimiter ";"

;***********************************



$findstr="LOC"

$delim=";"



$counter=0

while $counter<=ubound($groups) and $found<>1

  if instr($groups[$counter],$findstr)>0

    $found=1

    $descrip=split(getobject("LDAP://" +  $groups[$counter]).get("Description"),$delim)[1]

    ? $descrip

  endif  

  $counter=$counter + 1 

loop


Now all you should have to do is replace the variables and the ? $descrip line with whatever drive mapping you have. Hope this helps.
