is there anyone who tried to use ADOX (ADOX.Collection, ADOX.Users, ADOX.Groups) in Delphi?

I would like to find the information about users and groups in MS Access database. I have found a lot of info about ADOX in VB, but a few info about Delphi. I tried it myself, but without any success (i have imported the ADOX library, named the components well, but i couldn't connect it to the existing database.).
