Good morning list

I am having no end of problems trying to setup a delta synchronized replication. One consumer and one provider.

Symptoms are as follows:

User can authenticate and login using provider. If user changes password, new password does not get replicated to consumer. If password has not changed the user can authenticate and login using the consumer.

Provider configuration is as follows:

include /etc/openldap/schema/misc.schema include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/redhat/autofs.schema

include /etc/openldap/schema/ppolicy.schema

### added for host_attr access, this scheme gives me a host object for wrappers include /usr/share/doc/nss_ldap-253/ldapns.schema

# Allow LDAPv2 client connections. This is NOT the default. allow bind_v2 bind_anon_cred

# Do not enable referrals until AFTER you have a working directory # service AND an understanding of referrals. #referral ldap://root.openldap.org

The consumer configuration is as follows:

Error messages on the consumer is:

Aug 15 09:28:08 stgvir009 slapd[31110]: do_syncrepl: rid 000 retrying Aug 15 09:29:09 stgvir009 slapd[31110]: syncrepl_message_to_entry: rid 000 mods check (pwdAttribute: value #0 invalid per syntax) Aug 15 09:29:09 stgvir009 slapd[31110]: do_syncrepl: rid 000 retrying

Which looks like it is missing a schema. But I can't find a schema that is missing.

I don't know what this means I'm afraid. But intuitively it doesn't look good.

Any guidance would be astoundingly great. I am new to ldap so this is a bit of a learning curve.

Many thanks
