In test case 007 (Security - Security None) a comment says "test case says to create 5 more SecureChannels, but without Sessions!".

I haven't found anything in the specification that states minimum number of SecureChannels that a server shall support. Does anyone know of any such requirement and if so does the minimum number of sessions need to be the same?

We have entered a Mantis issue to define secure channels , not just session requirements as part of profiles.

https://opcfoundation-onlineap.....hp?id=4032

Currently most servers support at least as many SecureChannels as they do Sessions and most testing is based on this assumption, but you are correct in that it should be stated in the Profiles, not just assumed. Typically larger PC based Server (or any Servers that are not resource constraint) support more SecureChannels then Session limits. One suggest I have heard is 2 more SecureChannels then Sessions, but this will be discussed as part of the Mantis issue resolution.
