getent by definition is synchronous so it should wait.
we have timeouts right now because we may still have bugs in the
implementation and spots where we can't correctly catch if the operation
will ever successfully finish.

But the timeout is only a last resort measure and anything below 5
minutes is going to be more harm then help.
