The "$" is a defined syntax in RFC2252:

6.27. Postal Address

   ( 1.3.6.1.4.1.1466.115.121.1.41 DESC 'Postal Address' )

Values in this syntax are encoded according to the following BNF:

      postal-address = dstring *( "$" dstring )

   In the above, each dstring component of a postal address value is
   encoded as a value of type Directory String syntax.  Backslashes and
   dollar characters, if they occur in the component, are quoted as
   described in section 4.3.   Many servers limit the postal address to
   six lines of up to thirty characters.

   Example:

      1234 Main St.$Anytown, CA 12345$USA
      \241,000,000 Sweepstakes$PO Box 1000000$Anytown, CA 12345$USA



This applies to all attributes of syntax 'Postal Address', which may
include more than just the postalAddress attribute.  Now, whether all
clients are smart enough to follow this convention...  :)
