LDAP clients and handling of empty spaces

[Jens Vagelpohl <jens@digicool.com>]

hi everyone,

i am coming across a problem with some LDAP clients (notably those made by
micro$oft) where empty spaces in a DN that gets transmitted in order to bind
to the server with it are replaces with "%20" by the client.

since i assume there is no way to make those micro$oft clients play nice i'm
wondering whether i can tell slapd to convert the %20 back, or another
solution that would match the input with the correct DN in the database.
anyone ever had this problem?

input highly appreciated :)
