Full_Name: Oliver Loch Version: 2.4.31 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (88.134.36.68) Hello, first of all some basic information: OpenLDAP Version: [root@ls1 slapd.d]# slapd -V @(#) $OpenLDAP: slapd 2.4.31 (Apr 24 2012 01:06:25) $ nobody@ovide:/build/src/openldap-2.4.31/servers/slapd [root@ls1 slapd.d]# OS: Linux ls1 3.3.6-1-ARCH #1 SMP PREEMPT Sun May 13 10:52:32 CEST 2012 x86_64 GNU/Linux Distribution: ArchLinux What I'm doing: I have a Master/Master setup with actually two masters. To roll out the second master I created a small configuration that is added to the OpenLDAP database via slapadd. The config: ======>8========SNIP======================== dn: cn=config objectClass: olcGlobal cn: config olcServerID: 1 ldap://server1.foo.bar olcServerID: 2 ldap://server2.foo.bar dn: cn=module{0},cn=config objectClass: olcModuleList cn: module{0} olcModuleLoad: {0}back_bdb.la olcModuleLoad: {1}back_hdb.la olcModuleLoad: {2}accesslog olcModuleLoad: {3}memberof olcModuleLoad: {4}refint olcModuleLoad: {5}unique olcModuleLoad: {6}syncprov olcModulePath: /usr/lib/openldap dn: olcDatabase={0}config,cn=config objectClass: olcDatabaseConfig olcDatabase: {0}config olcRootDN: cn=master,cn=config olcRootPW: {SSHA}5e/wtWWZVQPCNf+92o8jYiO56wvh5cRQ olcSyncrepl: rid=001 provider=ldap://server1.foo.bar bindmethod=simple timeout=0 network-timeout=0 binddn="cn=syncer1,ou=users,cn=foo,cn=bar" credentials="supersecret" keepalive=0:0:0 starttls=no searchbase="cn=config" scope=sub schemachecking=off type=refreshAndPersist retry="5 +" olcMirrorMode: TRUE dn: olcOverlay={0}syncprov,olcDatabase={0}config,cn=config objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: {0}syncprov ===========SNAP========8<==================== When adding the configuration to the - empty - slapd.d configuration directory via: slapadd -F /etc/openldap/slapd.d -n 0 -l /root/base.ldif "slapadd" segfaults as soon as the "binddn" parameter inside the olcSyncrepl attribute contains things like "ou" or "dc". So using "cn=syncer1,ou=users,dc=foo,dc=bar" as binddn is not possible: =========SNIP=======>8======================= [root@ls1 slapd.d]# slapadd -F /etc/openldap/slapd.d/ -n 0 -l /root/base.ldif 4fb89a89 invalid bind config value binddn=cn=syncer1,ou=users,dc=foo,dc=bar 4fb89a89 olcSyncrepl: value #0: Error: parse_syncrepl_line: unable to parse "binddn=cn=syncer1,ou=users,dc=foo,dc=bar" . 4fb89a89 failed to add syncinfo slapadd: could not add entry dn="olcDatabase={0}config,cn=config" (line=19): _################# 86.13% eta none elapsed none spd 313.2 k/s Closing DB...Segmentation fault [root@ls1 slapd.d]# ===========SNAP========8<==================== But using "cn=syncer1,cn=users,cn=foo,cn=bar" is: ========>8==================SNIP============== [root@ls1 slapd.d]# slapadd -F /etc/openldap/slapd.d/ -n 0 -l /root/base.ldif _#################### 100.00% eta none elapsed none fast! Closing DB... [root@ls1 slapd.d]# ======SNAP================8<================= I played with it a bit and as soon as one adds "ou=..." or "dc=..." to the binddn it raises an error. In this example config and in the "real world". Imho there aren't any limitations to the binddn option? If you need further information feel free to contact me. Thanks! Kr, Oliver Loch
