I'm trying to make a plugin to pull all my ssh keys from our own secret service. I can see from this link (http://javadoc.jetbrains.net/teamcity/openapi/current/jetbrains/buildServer/TeamCityExtension.html) that ServerSshKeyManager is a subinterface of TeamCityExtension. So I registered my own extension:
However, none of methods is called when I tried to add or delete ssh keys. I wonder if this is the correct way of extending ssh key management or it is impossible to extend.
