"Bad certificate - SIC error 301 for lea" error when fetching 3rd party OPSEC server certificate from the Management server.
Traffic capture for the SSL negotiation phase between the servers shows the Management ICA is set to SHA-256.
Cause
The ICA signature hash algorithm of the Management server in $CPDIR/conf/sic_cert.p12 was set to SHA-256, then configured back with default SHA-1 hash. Per sk103840, OPSEC SDK does not support SHA-256 certificates.
