Known Affected Releases


Description (partial)

When Expressway-C verifies a cup-xmpp server certificate from IM&P that only has "Server Authentication", it fails the certificate check with error "Invalid Certificate Extension, Unsupported extendedKeyUsage ['TLS Web Server Authentication']". This should say something to effect of "TLS Web Client Authentication not present".

1.) IM&P server certificate for cup-xmpp only has "Server Authentication" in the Extended Key Usage field.

2.) "Enable XMPP Router-to-Router Secure Mode" is checked on the IM&P Security settings page.
