[jkupferer]

SUMMARY

Command to add users to groups can fail with a conflict if two simultaneous attempts are made to add users to the same group.

$ oc adm groups add-users OPENTLC-PROJECT-PROVISIONERS [email protected]
Error from server (Conflict): Operation cannot be fulfilled on groups.user.openshift.io "OPENTLC-PROJECT-PROVISIONERS": the object has been modified; please apply your changes to the latest version and try again

A simple ansible retries should resolve this issue.
