I need to provide authentication from the .NET Compact Framework application to a Windows Active Directory. But I figure out that there is no System.DirectoryServices Namespeace in the compact framework. Does anyone has any suggestion on providing a Active directory authentication to a smart client

How do I provide Active Directory Authentication in .NET Compact Framework 2.0?

Thanks Alex. The LDAP API supported by CE 4.2 and 5.0 allows me to login to AD. I ended up writing a COM wrapper for the API as you suggested. My project is for Pocket PC 2003 and the SDK provided by micrososft is missing the wldap32.lib. So I make my Mobile 5.0 (the file is there is the 5.0 sdk) working but is waiting for Microsoft to send me the file.
