sluprd and SASL

[FM <dist-list@LEXUM.UMontreal.CA>]

Hello,
I read several how-to but now I'm getting confuse.
I have 1 master and 1 slave
I want to replicate master to slave
on my slapd.confI have this example :

# Replicas of this database
#replogfile /var/lib/ldap/openldap-master-replog
#replica host=ldap-master:389 starttls=critical
#     tls=yes bindmethod=sasl saslmech=GSSAPI
#     authcId=host/ldap-master@EXAMPLE.COM


host/ldap-master@EXAMPLE.COM is the user (I suppose).
I have it in the keytab usedf by ldap and in krb5 db, but do I have to 
had it to ldap ?

Do you have a config examples (master and slave) that use : authcId ?

thanks !
