repmgr error trying to clone - permission denied

All;

I've installed repmgr, registered the master successfully and now I want
to clone the master as a standby.

My Master repmgr.cfg file looks like this:

$ cat repmgr.cfg
cluster=pg_test
node=1
node_name=node1
conninfo='host=192.168.182.132 user=postgres dbname=postgres'
pg_bindir=/usr/pgsql-9.3/bin

My master pg_hba.conf file:

# TYPE DATABASE USER ADDRESS METHOD

# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
host all all 192.168.182.133/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres trust
host replication postgres 127.0.0.1/32 trust
host replication postgres 192.168.182.133/32 trust
host replication postgres ::1/128 trust

The master is running on 192.168.182.132
I want the standby to be cloned onto 192.168.182.133

I ran this to register the master:

$ repmgr -f /var/lib/pgsql/9.3/repmgr/repmgr.cfg --verbose master register
Opening configuration file: /var/lib/pgsql/9.3/repmgr/repmgr.cfg

Here's my clone command:

$ repmgr -D /var/lib/pgsql/9.3/data -d postgres -U postgres -R postgres

I tried it without the -R as well, same result. I can connect from the
standby to the master via psql -h :

$ psql -h 192.168.182.132
psql (9.3.9)
Type "help" for help.

postgres=#

Thoughts?

Thanks in advance...
