I came across the same problem and my debugging shows the following:

1) ldap_groupcmp calls  radius_xlat to replace Ldap_UserDn with the value.
2) radius_xlat calls decode_attribute 
3) decode_attribute calls xlat_packet with instance 1 and returns 0 (=nothing found)
                if ((c = xlat_find(xlat_name)) != NULL) {                        if (!c->internal) DEBUG3("radius_xlat: Running registered xlat function of module %s for string \'%s\'",                                                c->module, xlat_string);                        retlen = c->do_xlat(c->instance, request, xlat_string,                                            q, freespace, func);                        /* If retlen is 0, treat it as not found */                        if (retlen > 0) found = 1;               }

If I look into xlat_packet there is a switch statement for instance and 1 means select request->packet->vps, but if I look into rlm_ldap.c the vps are in request->config_items (e.g instance= 0).  If I change instance to 0 in the debugger the expansion seems to work. Unfortunatly I don't know where this is set and what it means 

        switch (*(int*) instance) {        case 0:                vps = request->config_items;                break;

        case 1:                vps = request->packet->vps;                packet = request->packet;                break;

Hi,

We have upgraded our freeradius1.6 to 2.0

We are using active directory for LDAP server.

We have not changed any data in AD. But when we upgrade and try to connect using valid user id..user is getting rejected.

Please let me know if there any issues I need to take before ugprading to 2.0

Iam using same bind DN and other strings in 2.0.
