LDAP

Defines 110 Classes
Extends 113 Classes

This is a simple port of the San Joachin Delta College LDAP code into VW. The code has been moved into the NET namespace. Otherwise, the code is not changed.

1) The class structure, instance variable names, and most method names mirror their counterparts from the Netscape Java SDK. This allows enhancements to the original Java SDK to be made in the Smalltalk SDK more easily. It also allows leveraging of the original Java SDK documentation, which can currently be found at:

http://developer.netscape.com/docs/manuals/dirsdk/jsdk30/index.htm

One major departure is that embedded classes, notably classes LDAPConnThread and ResponseControl from the original LDAPConnection class, have been created as separate regular classes. Java interfaces have been ignored in this Smalltalk implementation.

2) See the examples on the class side of class LDAPConnection. Examples are provided for various types of inquiry and searching, iterating over results, support for LDAP URLs, add/modify/delete of directory entries, schema inquiry, and so on. The examples cover most of the common uses for the SDK in typical applications.

3) For better separation and packaging of code, all user interface classes have moved to the new parcel 'LDAPTestUI'

4) The LDAP over TLS implementation is provided by Cincom LDAPS package.

Questions can be addressed to Matt Rosen (mrosen@sjcoe.net)

KNOWN BUGS AND LIMITATIONS

A) Asynchronous search (i.e. specifying a batch size in the LDAPSearchConstraint other than zero) sometimes indicates that no more results are available when in fact they have just not arrived yet. Hack: Inserting a delay scaled based on the specified batch size in method

LDAPConnThread>>searchForDN:scope:filter:attributes:attributesOnly:constraints:

takes care of this problem (a comment for the delay appears in the appropriate location). When in doubt, use the default synchronous search.

B) Automatic following of LDAP referrals has not been tested.
