Calling 'SetPassword' needs two things: Kerberos and the correct permissions. You must be an adminstrator to call 'SetPassword' - which makes sense if you think about it. If you are passing the user's credentials to the DirectoryEntry and binding with them, you will be binding with the user's permissions and I doubt Adminstrator is one of them. This would also be why 'ChangePassword' works, because this call is intended for user's to change their own password. 'SetPassword' is much more powerful as it can override any password policy settings you have in place. Include your code for the DirectoryEntry and I might be able to point out any other issues. Also make sure you include your exact connection string to your LDAP source in your post (it makes a difference).
