Configuring SNC Between the UME and an ABAP-Based System
Use
You can set up the User Management Engine (UME) to use an ABAP-based SAP system as a data source for user management data. It is also possible to configure UME to replicate user data to an ABAP system. In both of these cases, the UME uses the Java Connector and RFC to connect to the ABAP system. To secure these connections, you use Secure Network Communications (SNC).
To configure SNC on these connections, follow the procedure described in Configuring SNC (SAP J2EE Engine ® ABAP Engine). When you get to setting the SNC parameters, use the procedure described below.
Prerequisites
Your UME is set up to use an ABAP system as its data source or you have set up UME to replicate user management data to an ABAP system.
Procedure
...
1.
Open the
UME property sheet for editing as described in
Editing UME
Properties.
2. Enter values for the following properties.
In the following property names the default value for <adapterID> for SAP systems used as a data source is master. You can check in the UME property ume.logon.r3master.adapterid whether it has been set to a different value
Property Name |
Description |
ume.r3.connection.<adapterID>. |
Required. Communication user in the ABAP system that is used for the connection to the ABAP system. Make sure that an SNC name has been entered for this user. For more information, see Requirements for Service User Used to Connect to SAP Systems. |
ume.r3.connection.<adapterID>. |
Optional. Location of cryptographic library. |
ume.r3.connection.<adapterID>. |
SNC name of SAP
User Management Engine. This is the distinguished name in the UME PSE in the
following format: |
ume.r3.connection.<adapterID>. |
Required. SNC name of ABAP
system. This is the distinguished name in the ABAP system’s SNC PSE in
the following format: |
ume.r3.connection.<adapterID>. |
Required. To activate SNC, this must be set to 1. |
ume.r3.connection.<adapterID>. |
Optional. Level of protection to use for the connection. |
3. When you have completed the SNC configuration, restart the J2EE Engine.
