Unless the script isn't reporting an operation between the error and the 
previous line, it is probably telling you that the entry 
cn="dc=company,dc=com",cn=mapping tree,cn=config doesn't exist.  Check 
your 7.1 server's dse.ldif file, it could be something like 
cn="dc=company, dc=com",cn=mapping tree,cn=config where the extra space 
is actually significant because it's within a value, not separating DN 
components.

I'm not familiar with the script but the replication manager entry is 
usually a normal person entry (with a userPassword) which gains a 
special role by its DN being specified in a replica configuration.  
Replication agreements use this identity to bind to peer replicas and 
send special extended operations to initiate replication sessions.
