Expressway 8.10 Number of metadata files

[sheepate]

The configuration guide for Expressway to enable SSO for MRA states that the metadata file needs to be exported from Expressway-C(Primary).

Is that the only meta data file that needs to be exported? When I look at the meta data files from other C nodes in the cluster, the signing and encryption keys are different.

Did you ever get an answer to this? The documentation is unclear.

In the cluster guide it references if you add a node that was previously SSO integrated you need to regenerate the Xml and import.
