I am preparing a bit for setting up replication. However when I manually

try to dsync an account, the first time I execute this[1] command it

seems to be ok. The 2nd time I am getting this error[2].

If I add -1 (one way syncing) the error disappears. Does this mean I

will have problems with setting up replication between these two

servers?
