Replication problems.

[Chris Burnley <chris@viator.com>]

I am running OpenLDAP 2.0.7 on linux (compiled from source), and finding that 
replication doesn't work. I have also tried this with 2.0.6 obtained from the 
linux-mandrake cooker. Never tried it with 1.2.x.

I am running two slapds one on port 3890 ( master ) and one on port 3891 
(slave) on the same host.

( with secrets replaced with < name > )

in slapd.conf.3890 (master) ( symbolicly linked from slapd.conf ):

< schema includes >

replica host=127.0.0.1:3891 binddn="<bind address> " bindmethod=simplec 
redentials=<a secret password> 

replogfile /var/log/slapd.replica

in slapd.conf.3891 (slave): 

< schema includes >

updatedn "dn=admin,dc=viator,dc=com"
updateref "ldap://127.0.0.1:3890";                   

< rootdn the same as slapd.conf.3890 >

I then startup the master and slave

/usr/sbin/slapd -h ldap://127.0.0.1:3890 -f /etc/openldap/slapd.conf.3890
/usr/sbin/slapd -h ldap://127.0.0.1:3891 -f /etc/openldap/slapd.conf.3891

Then from running

"slurpd -d 255 -f /etc/openldap/slapd.conf.3890"

I am seeing :

begin replication thread for 127.0.0.1:3891
Replica 127.0.0.1:3891, skip repl record for propertyName=host, 
propertySet=connectionsource, application=etravel, instance=default, 
dc=viator,dc=com (not mine)

It is saying that it added replica ( which is the correct address), but when 
adding some debug statements, in servers/slurpd/ri.c,  I find that the 
re->re_replicas is NULL. How can this be so?

This is my modified ismine function:

static int
ismine(
    Ri  *ri,
    Re  *re
)
{
    Rh  *rh;
    int i;
    if(1) return 1;

    Debug(LDAP_DEBUG_ANY,"rc.c:206, ismine\n",0,0,0);
    if ( ri == NULL || re == NULL || ri->ri_hostname == NULL ||
            re->re_replicas == NULL ) {
      if (ri == NULL)
            Debug(LDAP_DEBUG_ANY,"ri == NULL\n",0,0,0);
      if (re == NULL)
            Debug(LDAP_DEBUG_ANY,"re == NULL\n",0,0,0);
      if (ri->ri_hostname == NULL)
            Debug(LDAP_DEBUG_ANY,"ri->ri_hostname == NULL\n",0,0,0);
      if (re->re_replicas == NULL)
	// THIS LINE IS PRINTED OUT
            Debug(LDAP_DEBUG_ANY,"re->re_replicas == NULL\n",0,0,0); 
        return 0;
    }
    Debug(LDAP_DEBUG_ANY,"rc.c:211, cmp : %s,%d\n", 
ri->ri_hostname,ri->ri_port,0);
    rh = re->re_replicas;
    for ( i = 0; rh[ i ].rh_hostname != NULL; i++ ) {
        Debug(LDAP_DEBUG_ANY,"rc.c:214, host: %s:%d\n",rh[ i 
].rh_hostname,rh[ i].rh_port,0);
        if ( !strcmp( rh[ i ].rh_hostname, ri->ri_hostname) &&
                rh[ i ].rh_port == ri->ri_port ) {
            return 1;
        }
    }
    return 0;
}                                                                             
                                                                 

Any help would be appreciated,
