I am currently running a c# .NET Core 2.1 application on OpenShift.

My application connects to Mongo on the Linux container, when using plain authentication.

When I try to GSSAPI with a keytab file I get the following error

Error: One or more errors occurred. (A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector, LatencyLimitingServerSelector

Should the version running on Linux be looking for the security.dll?

 

I have following the instructions on the following page
