LDAP as the UME data source - ABAP data source automatically configured

[Former Member]

Hi,

I have installed SAP NetWeaver 7.0 SR2 + MaxDB with AS-ABAP, AS-JAVA, BI-Java, DI, EP, EPC on Linux SLE9 on IBM on Power. The server is only use as a Portal.

I should like to configure Microsoft ADS (LDAP) as the UME data source. After the installation I start the server and the portal is running well. Now I would like to change the UME data source to LDAP but the ABAP data source is already configure.

Why is the ABAP data source automatically configure? It´s not possible to change the ABAP data source.

In the SAP Setup (sapinst) was no option to choose the UME data source.

On witch point and time can I configure LDAP as the UME data source?

Thank you very much for your help!

Hi,

I think you should have been able to configure the UME of the J2EE Engine to use database and not the ABAP system.

A switch from this datasource is not supported (see Note 718383 - NetWeaver: Supported UME Data Sources and Change Options).

In theroy it should be possible to change the datasource that is used via the configtool.

Hey Holger,

Thanks for your replay. Sorry, I don’t understand your answer.

In the configtool => UME LDAP data => The Option "Configuration file" is set to "dataSourceConfiguration_abap.xml" and deactivate. I’m not able to change this option. Any ideas?

Is it necessary to upload a xml file? How can I download the xml file?

THANKS!

Hi,

with the configtool you change the datasource. Open the configtool -> switch to editor mode -> cluster data -> server -> cfg -> services -> Propertysheet com.sap.security.core.ume.service. In this box you can change ume.persistence.data_source_configuration to dataSourceConfiguration_database_only.xml.

Then you should be able to work from there!

But remember: this is not supported! And if you change this all your userinformation / mapping will be gone. Make a backup before you change this and run a UME consistency check after the change.

Regards,

Holger.

And the reason it has automatically chosen ABAP is the datasource is becuase you have done a AS-ABAP & AS-JAVA install i.e. AS_ABAP with AS-Java as an add in. In this scenario it always sets ABAP as the datasource. If you want it to not do that, you much install java on it's own.

I have done what Holger is suggesting... although it is probably better to change to a ldap + db configuration because you need to re-create users such as J2EE_ADMIN and J2EE_GUEST else it will not start.

As Holger says though, it is not supported so if fine for a sandpit / playbox, but nothing else.

Hi Paul,

Thanks a lot for your reply.

Do you mean I have to install only AS JAVA without any ABAP on the same server?

Hi,

if you did not chose an Java-AddIn Installation (where the UME is always connected to the ABAP system) then there really should be a screen during the installation which asks you where you want the UME to connect to: ABAP or Database / LDAP.

There you should be able to choose the latter.

Ruven,

reading help is believing......... so check this out

During Installation

During installation of the SAP NetWeaver Application Server (AS), you can choose among the following data sources for the UME:

1. Database of the AS Java

This data source is selected if you choose the usage type AS-Java without the usage type AS-ABAP during installation.

1. User management of the AS ABAP

This data source is selected if you choose the usage type AS-ABAP in addition to AS-Java during installation.

After Installation

After installation, you can change the data source of the UME. The following data source changes are supported:

1. From the AS Java database to user management of an AS ABAP

2. From the AS Java database to a directory serve

Once you have selected a data source other than the AS Java database, you cannot change the data source of the UME. Under certain circumstances you can make modifications to the data source as follows:

1. For a directory service as data source, you can change the directory service structure or change to another directory service.

2. For an AS ABAP data source, you can change which data source configuration file is used or change the AS ABAP used as the data source.

Thanks for your answer!

I installed a new server only with AS Java, EP & EPC. Now I can choose during the installation UME-DB-only. GREAT!

Is it now possible to install additional an AS ABAP?
