Checking server cert CN

Howdy,

 

Running 10.2.4 still and looking to find any way to validate a server certificate name. There's the "Authenticate Name" option on the serverssl profile, however we have multiple endspoints each with a site specific DN on their cert. I'd check that a consistent name is present as a SAN, but get the impression that the SAN list isn't checked with Authenticate Name? What about Wildcards or regexes in that field?

 

SSL::cert does not work on server side calls right? So is there no possible iRule based appraoch to this either?

 

Thanks

 

Chris

    just checked this and it works fine on server side. what doesn't work well on server side is the SSL::verify_result

      good point, don't have that version around to test. have you tried on 10.2.4, do you get an error or nothing?

      Error, says it can't evaluated in that context if I remember right.
