3531793 - Open Client: Client incorrectly validates non-matching client side Common Name and Server side Common Name - SDK for SAP ASE

• Open Client connects require the ASE's Common Name that started the port be the same as the Client side Common Name given in the filter
• However Open Client allows a miss match to be validated when the Common Name value is off by 1 character at the end.
• Example:
  • ASE's $SYBASE/interfaces
    • master tcp ether asehost aseport ssl="CN=ASEname"
  • Open Client's $SYBASE/interfaces
    • query tcp ether asehost aseport ssl="CN=ASEnam"

• SAP Adaptive Server Enterprise (ASE) Software Developer Kit (SDK) 16.0
• Open Client Client-Library
• ctlibrary
