looking for entires with objectclass=glue

Hello, I've running two ldap server using N-Way multimaster replication. I want find all objects with "objectclass=glue". If I use JXEplorer to search "objectclass=glue" I get 136 entries back. If I use ldapsearch or Apache DS and do the same, no entries are found. In the slapcat backup from the ldap server the entires with objectclass: glue exists. So I turned "loglevel 256" in the slapd.conf. I got for JXEplorer and ldapsearch the same search: JXEplorer: slapd[23362]: conn=1001 op=7 SRCH base="ou=root" scope=2 deref=3 filter="(objectClass=glue)" slapd[23362]: conn=1001 op=7 SRCH attr=objectClass slapd[23362]: conn=1001 op=7 SEARCH RESULT tag=101 err=0 nentries=136 text= ldapsearch: slapd[23362]: conn=1004 op=1 SRCH base="ou=root" scope=2 deref=3 filter="(objectClass=glue)" slapd[23362]: conn=1004 op=1 SRCH attr=objectclass slapd[23362]: conn=1004 op=1 SEARCH RESULT tag=101 err=0 nentries=0 text= How can I get the glue entires via ldapsearch? Thanks Andreas
