The article will explain how changing the ciphers and algorithms in OBM for the LW-SSO integration with NNMi can break the APM integration and what needs to be done to fix that.

Environment

Operations Bridge Manager (OBM) 2023.05
Applications Performance Manager (APM) 9.60

Situation

There are OBM and APM integrated using LW-SSO. It was working but after OBM to NNMi LW-SSO integration  the data in the APM components is not being showed. The components are opening empty. 

Cause

NNMi has moved to a more secure, FIPS compliant crypto algorithm for LWSSO encryption and decryption. The library in OBM will fail to decrypt NNMi's LWSSO key encrypted with the updated crypto functions. To complete the integration, one needs to upgrade the crypto functions in OBM to match that of NNMi. One needs to change this in the OBM LW-SSO to use the new algorithms. Once that is done the APM LW-SSO integration will not work unless you do the same steps and configuration in APM. See:

Part Update the LWSSO XML file on OBM.
