user validation throug active directory (LDAP)

[machocr]

Hi, I need to validate users throug active directory in asp.net 2.0. The users will be on diferents locations and dommains. The users aer part of differents companies with differents dommains, so for a single user I need to search the company at database and load the company settings to be able to do the authentication by active directory. Is that possible? Which active directory settings do I need to store for each company? How can I do that validation? I have the following snippept: 1. public bool AuthenticateUser(string domain, string username, string 2. password) 3. { 4. string domainAndUsername = domain + @"\" + username; 5. DirectoryEntry entry = new DirectoryEntry( LDAPPATH, 6. domainAndUsername, 7. password); 8. try 9. { 10. // Bind to the native AdsObject to force authentication. 11. Object obj = entry.NativeObject; 12. DirectorySearcher search = new DirectorySearcher(entry); 13. search.Filter = "(SAMAccountName=" + username + ")"; 14. search.PropertiesToLoad.Add("cn"); 15. SearchResult result = search.FindOne(); 16. if(null == result) 17. { 18. return false; 19. } 20. // Update the new path to the user in the directory 21. LDAPPATH = result.Path; 22. } 23. catch (Exception ex) 24. { 25. throw new Exception("Error authenticating user.” + ex.Message); 26. } 27. return true; 28. } Is the code I need? can you explain me how to contruct LDAPPATH? Thank you I'm very newie with AD.:confused:
