Question: MIC cannot be validated; Possible old Cisco CA?
I tried to install a LSC on a Telepresence MX300 unit. I didn't work until I changed the "Authentication Mode" to "Null String". First it was set to "By existing Certificate (precedence to MIC)" which never worked. (Error: Invalid credentials...)
My guess would be that the MIC installed on the unit cannot be validated by CUCM. Here is a excerpt of the certificate:
Version: 1 (0x0)
Signature Algorithm: sha1WithRSAEncryption
Issuer: C=US, O=Cisco Systems, Inc.
Not Before: May 6 10:16:47 2014 GMT
Not After : Apr 12 10:16:47 2114 GMT
Subject: C=US, O=Cisco Systems, Inc.
Subject Public Key Info:
Public Key Algorithm: rsaEncryption
Public-Key: (2048 bit)
We have the standard Cisco root CAs installed on our system:
Any ideas as to why it fails with the MIC validation?
