Full_Name: Emmanuel Duru Version: 2.3.39 OS: Windows URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (195.68.44.148) When the provider server receives a modify RDN operation, syncrepl replicates it with the full new DN as new RDN. Trying to investigate it, I see that syncrepl.c:syncrepl_entry() gets the newrdn from a call to dnRdn() function, which only modifies the bv_len of the ber struct, but not the value itself. Following this, the backend:be_modrdn() function does not check the length, and gets the full DN as RDN value (at least back_ldap does this).
