SAP Identity Authentication vs. Local Identity Directory - Differences

[tskwin]

Hello All,

What is the difference between SAP Identity Authentication and Local Identity Directory in SAP IPS/IAS ?

In both cases, users are stored in SAP IAS, but I don't understand the difference and when each solution should be used.

Thank you very much!

BEst Regards

Besides the differences in my other post, I realized a different one, an important one.

The IAS-one can be used to connect to other systems, like when keeping two IAS's in sync.
Whereas the Local Identity Directory can only be 'itself'.
