syncrepl binds with no password

I'm trying to setup a simple replication. I configured syncrepl in the consumer to use the user syncuser to access the master ldap but when it connects to the master it does not send the password for syncuser, so the master errors with:

unauthenticated bind (DN with no password) disallowed

Here's the replication definition in the consumer:

syncprov-checkpoint 100 10 syncrepl rid=000 provider=ldap://192.168.77.218 type=refreshOnly interval=00:00:02:00 retry="5 5 300 +" searchbase="dc=idi-test,dc=com" attrs=* bindmethod=simple binddn="uid=syncuser,ou=People,dc=idi-test,dc=com" credentials={SHA}jHXtTHIeoSUGGge0YOB5dJQeXf4=

What am I missing?
