[Explain Lightweight Directory Access Protocol.]
There are four (?) independent implementations, ldapTcl, Matt Newman's LDAP extension [L1 ], Jochen Loewer's (see below) and the one available in tcllib as of 2004.
[And http://www-users.aston.ac.uk/~oweng/tclLdap-pkg/ , also?]
I did a pure Tcl implementation of a ldap interface in June 99. See (Jochen Loewer). It is running since then very nicely to query a large enterprise wide people directory. Right now only the read/query parts of the protocol are implemented. However, the internal ASN layer is there, so it should be rather easy to extend it. Unfortunately I didn't release the code to the public yet. I thought about that several times. It would be ideal for tcllib or even standard tcl (like the http package). CL: ooooo. ASN.1 would be nice for tcllib.
