If the bug is not specifically in the OpenLDAP software, I suggest you peruse: <http://www.openldap.org/support/> I would note I don't see anything particular in what you provide indicating the problem is with ldapsearch. What version of OpenLDAP is the server in question running (I see it is OpenLDAP by querying its rootDSE)? I'll note that a *limited* ldapsearch works just fine: [quanah@freelancer ~]$ ldapsearch -x -H ldap://exp-bdii.cern.ch:2170 -b "" -s base + # extended LDIF # # LDAPv3 # base <> with scope baseObject # filter: (objectclass=*) # requesting: + # # dn: structuralObjectClass: OpenLDAProotDSE namingContexts: o=grid supportedControl: 2.16.840.1.113730.3.4.18 supportedControl: 2.16.840.1.113730.3.4.2 supportedControl: 1.3.6.1.4.1.4203.1.10.1 supportedControl: 1.2.840.113556.1.4.1413 supportedControl: 1.2.840.113556.1.4.1339 supportedControl: 1.2.840.113556.1.4.319 supportedControl: 1.2.826.0.1.334810.2.3 supportedExtension: 1.3.6.1.4.1.1466.20037 supportedExtension: 1.3.6.1.4.1.4203.1.11.1 supportedExtension: 1.3.6.1.4.1.4203.1.11.3 supportedFeatures: 1.3.6.1.4.1.4203.1.5.1 supportedFeatures: 1.3.6.1.4.1.4203.1.5.2 supportedFeatures: 1.3.6.1.4.1.4203.1.5.3 supportedFeatures: 1.3.6.1.4.1.4203.1.5.4 supportedFeatures: 1.3.6.1.4.1.4203.1.5.5 supportedLDAPVersion: 2 supportedLDAPVersion: 3 supportedSASLMechanisms: DIGEST-MD5 supportedSASLMechanisms: CRAM-MD5 subschemaSubentry: cn=Subschema # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 [quanah@freelancer ~]$ I would also note that for me, doing a dump of the entire server works just fine: ldapsearch -x -H ldap://exp-bdii.cern.ch:2170 -b "o=grid" results in: # search result search: 2 result: 0 Success # numResponses: 43962 # numEntries: 43961 Adding -d -1 to the query, I eventually see the same thing you do: ber_get_next failed. wait4msg continue ld 0x233f0e0 msgid -1 all 0 ** ld 0x233f0e0 Connections: * host: exp-bdii.cern.ch port: 2170 (default) refcnt: 2 status: Connected last used: Wed May 14 09:34:06 2008 ** ld 0x233f0e0 Outstanding Requests: * msgid 2, origid 2, status InProgress outstanding referrals 0, parent count 0 ** ld 0x233f0e0 Response Queue: Empty ldap_chkResponseList ld 0x233f0e0 msgid -1 all 0 ldap_chkResponseList returns ld 0x233f0e0 NULL ldap_int_select read1msg: ld 0x233f0e0 msgid -1 all 0 ber_get_next ldap_read: want=1142, got=0 ber_get_next failed. ldap_perror ldap_result: Can't contact LDAP server (-1) ldap_free_request (origid 2, msgid 2) ldap_free_connection 1 1 ldap_send_unbind ber_flush: 7 bytes to sd 3 0000: 30 05 02 01 03 42 00 0....B. ldap_write: want=7, written=7 0000: 30 05 02 01 03 42 00 0....B. ldap_free_connection: actually freed --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration
