Hi Experts,
We have a EP6 Portal system, connected to a ECC5 backend, running ESS/MSS/LSO, etc.. Currently the UME is set as dataSourceConfiguration_abap.xml, which allows only ECC5 users to logon to the portal.
We now have a requirement to change the UME to dataSourceConfiguration_ldap (to enable implementation of Single sign-on, authenticating from the local Active Directory).
I've come across note 718383, as well as sap.help.com, indicating that the UME cannot be changed, once abap has been selected.
In a test environment though it seems to be possible to do the above change.
Does anyone know why this change is not recommended, or what the inconsistencies is that will occur if this change is implemented ?
