Can't set up witness in Repmgr 2.0

I am trying to setup repmgr using the autofailover quick setup tutorial provided on Github Link

But I am kind of stuck on the witness section, when trying to create the witness with repmgr -d repmgr -U repmgr -h [MASTERIP] -D /var/lib/postgresql/9.1/witness -f /var/lib/postgresql/9.1/repmgr/repmgr.conf witness create

I get the following error:

Connection to database failed: fe_sendauth: no password supplied

I am not sure which database the error is talking about? Is it the master’s DB or the witness’?

Also, I haven’t been able to find a password parameter to pass to repmgr yet, is there even one?

Below are the repmgr.conf files for each server:
