Connectors are not part of the ITPAM install any more.
In early versions of ITPAM, there were several connectors that were part of the orchestrator install. As of ITPAM 3.1, the connectors are available from the best practices web site which can be accessed here: https://support.ca.com/phpdocs/0/common/impcd/r11/Catalyst/ITPAM_Frame_sc.htm.
In addition to the connectors listed on this site, there are premium connectors that can be accessed for a fee. Please contact your account representative to access these connectors.
