Maximum Number of UME (LDAP) Data Sources?

Hi,

We currently have 3 seperate LDAP domain datasources configured in our custom UME XML file for our SAP portal. There is an upcoming need for 2 additional domains, which will put us to the maximum of 5 allowed according to a few OSS notes.

Has anyone had to deal with this limitation? Is it a real hard limitation or a suggested limit by SAP? Is SAP planning on increasing this maximum? What are other folks doing to get around this limitation?

I would think in today's environment of increased M&A activity someone else out there has a need to service more than 5 domains with one portal.

Thanks,

Ashley Williams
