Accessing the Active Directory (AD) from Delphi

[Kenbla]

Hello, I'm responsible for a Delphi XE application which handles users and user administration. It accesses the AD when users are added, modified or when new passwords are set etc.
All these methods are very slow! It takes minutes to perform them sometimes up to 10-15 minutes which is very frustrating for the users.
The AD methods we use from our Delphi application are:
- NetUserSetInfo (defined in netapi32.dll)
- SetInfo
There are also some other AD methods that we use.
I pass parameters to the methods accordingly and it works fine but it takes forever!

Does anyone of you have any advice and/or recommendations to us?
Thanks,
Kenbla

Not certain what it could be.
If I were you I would run some wireshark traces on a client PC running your app and see if there is some SSL handshaking going on in the background, SSL handshakes are known to be very slow.
Are you using the LDAP provider or WinNT provider?

Hi Daddy! and thanks for your reply.
We use LDAP.

I have verified my code once again and discovered that we are using a combination of WinNT and LDAP! and I don't know if that's good or bad!
Are there any major code changes that I have to do if I want to use WinNT instead of LDAP?
My LDAP code currently looks like this:
AdsDomain := GetObject('LDAP://cn=users,DC='+sDomainName +',DC=se') as IADsContainer ;
DomainPath := 'LDAP://OU='+sInputOU+',DC='+sInputDomainName+',DC=se';
AdsDomain := GetObject('LDAP://'+sInputDomainName+'.se') as IADsContainer ;
