The SAP program RSLDAPSYNC_USER is a tool that allows you to synchronize user data between an LDAP directory and the SAP system.

This program can be used to:

  • Transfer user data from the LDAP directory to the SAP system

  • Update user data in the SAP system if changes are made in the LDAP directory

  • Delete user data in the SAP system if the user is removed from the LDAP directory


In order to do that, you have to do the Mapping in the LDAP t-code.

Here are the steps to perform the mapping in SAP LDAP:

Step 1 : 

Mapping in SAP LDAP refers to configuring the correspondence between attributes in an SAP

system and attributes in a Lightweight Directory Access Protocol (LDAP) directory used to store information.

Step 2 : 

We have 4 area that 2 of them are Mandatory to fill in order to do the Mapping well.

A) Syst.SAP :

  • Unique key, if it is used in another part in the configuration table, it cannot be reused.

  • Name of the table & the zone: in this part it is necessary to select the data that we want to do the mapping with  SAP .

Example for the Mapping of email field:

We use Table : ADDRESS and field :  E_MAIL

B)  directory:

  • Also Unique key, if it is used in another part in the configuration table, it cannot be reused.

We must choose the LDAP attribute to synchronize the mail. we have 2 options to do this :

  • If we have the correct mail in LDAP and do not require any modifications, we only put it in this part.

Exemple : if in LDAP we have  : .

  • if we need to make management rules or concatenate fields to build the email, we must fill theses fields in the Attribute Directory and we must use the Function Module.

Exemple  : we should concatenate firstname . lastname @ attributeX . FR .

In this case fistname lastname attributeX we must add them to the Attribute directories and use the Function Module to do the concatenation to create the correct mail .

C)  Function Module :

must be created based on the standard ( MAP_CONSTANT ) to properly manage the output of the mail Table ( Attributes) .

D) Setting : 

When a mapping uses a function module to map database fields, parameters can be passed to the function module.

Overall, RSLDAPSYNC_USER can be a useful tool for organizations that need to synchronize user data between LDAP and SAP, helping to streamline workflows and improve data accuracy.
