Re: Valid characters in username and password?
OpenLDAP client tools, and underlying client library routines,
expect filters to be presented using the string representation
detailed in RFC 2254. See RFC 2254 for details on how to escape
characters special to this representation. Of course, as you
likely are passing these strings through a command line, or
a programming language, you may also need to escape characters
of the string special to the interface.
