I removed the synrepl from a ldap server.  Now I am getting errors when deleting entries

ldap_modify: Server is unwilling to perform (53)
        additional info: shadow context; no update referral


I also tried adding this, but does not change anything.

dn: olcDatabase={0}config,cn=config
changetype:modify
add: olcMirrorMode
olcMirrorMode: FALSE

I don't think it is the acl's as I was able to change logging level before, when it was a slave. However now I am also not able to update the logging level.

What config settings should I look at?
