Hi, PowerObject. I've tried succesfully your LDAP code. Thanks a lot! Once succesfully connected to the LDAP server, how to make querys for specific users to check they're valid ones?

Updated with more screenshots. See below...

Attaching w_Login.txt (rename this to .srw) and n_cst_Login.txt (rename this to .sru) with options to perform LDAP and Active Directory logins. The code is exported from PowerBuilder 2017 for forward compatibility during import into later versions. The login window is implemented using non-intrusive status messages for better UX.

Once login is successful using network creds, go ahead and connect to the dB implicitly using a common dB User with sufficient privileges (especially useful in 3-Tier PowerServer apps and SSO).

If you make too many unsuccessful login attempts, you could get locked out of Windows!

For 2-Tier dB login, you could disable the Domain SLE (or replace it with a DDLB of databases) and use the Username and Password fields to directly log into the dB by altering some logic in of_Login().

On PowerBuilder 2022, window size is messed up - re-align the controls and status bar as needed.

Ignore the functions starting with xf_* or discard them.

There is a Themes DDLB too on the login screen - uncomment the ApplyTheme() call in of_ApplyTheme() if using PowerBuilder 2019 or later, if needed.

Assign logo, image and modify the Copyright text.

For people with color blindness, adjust the UI colors.

Hello Appeon, we cannot attach .srw or .sru or any PowerBuilder source files? Not even TXT files?

You can do LDAP authentication using VB Script and OLE Automation inside PowerScript.

You can also do Active Directory authentication using LogonUser() API function.

You'll find the code for both the above methods online.
