Hello everyone!
Could somebody give step-by-step manual how to configure ldap connection and user mapping in abap system?
Current sitation:
1. Configure LDAP Connector
2. Create System User
3. Configure LDAP Server
This part is done and works fine...
But what should i do next?
I want to use for mapping ExtensionAttribute3. And i dont want to change AD schema (or i have to do it anyway?)
I found few manuals but they are different...
In one of them i found as a next step:
"Navigate to transaction SPRO and select SAP Customizing Implementation Guide.
Drill down to SAP Netweaver->Gateway-> Generic Channel->Configuration->Consumer Settings->Select User Mapping Type.
Add a new entry and enter LDAP based user mapping, LDAP server you created in the previous steps and the LDAP attribute to be used for mapping."
But i dont have this menues in SPRO...
In other manual i have to go to transaction LDAPMAP. It looks like in this case i need some XML file with mapping attributes, after that i need to make this feel mapping. And then i have to set synchronization account from AD to ABAP. But i dont understand where i can get XML file and i guess in this file should be ExtentionAttribute3 as a mapping attribute...
So... I will be very appreciate for any assistance! 
Thank you in advance!
