add a TN3270 configuration option to disable the check for Server name & Certificate name to match

Configurable  Option to disable Verify Certificate

We have encountered a situation with our TKEs at RBC.

We had LPAR site certificates included in the TN3270 ring before and removed thus only TN3270 user certificate is in the keyring.

More specifically, if a user connected TN3270 on TICF, TICF site certificate(ticf.fg.rbc.com) was sent to the clients and if tnocc was targeted then tnocc.fg.rbc.com certificate was sent.

Now no matter what a user targets tnocc or a lpar, only tnocc.rbc.com certificate is sent.

 

Recently we changed our Certificate names to drop the .fg , as part of some security requirement, so we no longer reveal our dns. We used to be tnocc.fg.rbc.com, but now are tnocc.rbc.com

As a result, our Hostname (Server Name: tnocc.fg.rbc.com) does not match the CN (Certificate Name: tnocc.rbc.com) for our TN320 certificate

This causes an authentication error (Certificate Name mismatch) when we try using the TN3270 certificate to configure our TKE 3270 session

We would like a TKE menu where we can edit the SSL properties similar to what PCOMM has to disable the check for Server name & Certificate name to match
