HowTo index generalizedTimeOrderingMatch
by Meike Stone 07 May '12

07 May '12

Hello, I have in my own schema an attribute defined: attributetype (1.3.6.1.4.... NAME ('InsertTime') EQUALITY generalizedTimeMatch ORDERING generalizedTimeOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.24 ) Now I can use this and search, but it takes very long. So I want index it for searching: * greater (">=") * less ("<=") Is it possible and how can I do this? I have only seen "eq" and "pres". Thanks in advance Meike

openldap to AD proxy
by Alex Samad - Yieldbroker 04 May '12

04 May '12

Hi I am still struggling with the my openldap to AD proxy connection. I have successfully connected such that I can do search when I bind to openldap with an AD dn, but I want to be able to do anon search and I want anon to map through to a dn I have created in AD which has read only rights. dn: olcDatabase={3}ldap,cn=config objectClass: olcDatabaseConfig objectClass: olcLDAPConfig olcDatabase: {3}ldap olcAccess: {0}to * by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage by * read olcReadOnly: TRUE olcRootDN: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth olcSizeLimit: 500 olcSuffix: dc=xyz,dc=com olcDburi: "ldap://ldap. xyz.com " olcDbRebindAsUser: TRUE olcDbChaseReferrals: TRUE olcdbaclbind: bindmethod=simple binddn="CN=ad readonly,OU=YB Services,OU= xyz,DC= xyz,DC=com" credentials=":)" starttls=no olcDbIDAssertBind: bindmethod=none binddn="CN=ad readonly,OU=YB Services,OU= xyz,DC= xyz,DC=com" credentials=":)" starttls=no I have a subordinate db at ou=external, DC= xyz,DC=com I can do a ldapsearch -x -D " CN=ad readonly,OU=YB Services,OU= xyz,DC= xyz,DC=com" -b " DC= xyz,DC=com" -w :) what I can't do is ldapsearch -x -b " DC= xyz,DC=com" I am thinking I want to map anon request through to the readonly DN. But still leave it such that when people bind to openldap as themselves they bind to AD as themselves How would I do that ? Thanks Alex

SMB+OPENLDAP
by Alejandro Iacobelli 03 May '12

03 May '12

Hello to all, my name is Alejandro and I have a little question to anyone of this list. I´ve created ,6 years ago, an ldap+smb proyect for a big company. Back then, samba (Lenny server) only worked with NT hashes but now (Squeeze server) they want to authenticate with Win7 (ntlm2 protocols) And configurating windows7 to accept old NT hashes is not an exit. I want to update ONLY the smb package from samba (2:3.2.5-4lenny15) to samba (2:3.5.6~dfsg-3squeeze8). My question is this: Can you give me some information about if openldap could crash if only I update the samba module and not the ldap one? i need to know if something could go wrong in the relation with openldap. ( I will not touch openldap because i've modified that version by myself ).

Michael, Thanks for your help. We found that it was the audit log that was slightly over 2GB, so I cleaned that up and it is good now.

I am running OpenLDAP 2.4.11 and I am getting an error when I attempt to modify, delete, or add to the directory with a credentialed user (has worked for the past few years perfectly). I did a debug-level report on the server and it's giving me with respect to my modify request, I am getting the following results: bdb_modify: updated id=00013892 dn="mbiUniqueID=669103f11bb82ef68f6adbcf75216c1b,ou=people, dc=XXXXXX,dc=XXX " send_ldap_result: conn=1057 op=1 p=3 send_ldap_result: err=0 matched="" text="" => bdb_entry_get: ndn: "mbiUniqueID=669103f11bb82ef68f6adbcf75216c1b,ou=people, dc=XXXXXX,dc=XXX " => bdb_entry_get: oc: "(null)", at: "(null)" bdb_dn2entry("mbiUniqueID=669103f11bb82ef68f6adbcf75216c1b,ou=people, dc=XXXXXX,dc=XXX ") => bdb_entry_get: found entry: "mbiUniqueID=669103f11bb82ef68f6adbcf75216c1b,ou=people, dc=XXXXXX,dc=XXX " bdb_entry_get: rc=0 => test_filter PRESENT => access_allowed: search access to "mbiUniqueID=669103f11bb82ef68f6adbcf75216c1b,ou=people, dc=XXXXXX,dc=XXX " "objectClass" requested <= root access granted => access_allowed: search access granted by manage(=mwrscxd) <= test_filter 6 syncprov_matchops: sid 000 fscope 1 rc 6 ./slapd-PRODM1: line 227: 26203 File size limit exceeded$SLAPD_BIN -h "$SLAPD_SERVICES" $SLAPD_PARAMS slapd-PRODM1[26473]: [ALERT] slapd not running Also, the service script in /etc/init.d is named slapd-PRODM1.

DEL don't get synced
by Marc Patermann 02 May '12

02 May '12

Hi, under some circumstances DEL don't get replicated to the consumers (SyncRepl). I think this has to do with other changes at the some moment. I attached two logs excepts in sync.log. In the first except there is only a DEL Jan 31 09:16:01 ldapserver slapd[10641]: conn=79138 op=2 DEL dn="employeeNumber=19676,ou=humans,ou=foo" For this there is a Jan 31 09:16:01 ldapserver slapd[10641]: syncprov_sendresp: cookie=rid=401,csn=20120131081601.377028Z#000000#000#000000 line for every connected consumer. In the second step there is a MOD and a DEL Jan 31 10:31:01 ldapserver slapd[10641]: conn=79938 op=2 MOD dn="ou=FA-WF,ou=gruppen,ou=humans,ou=foo" Jan 31 10:31:01 ldapserver slapd[10641]: conn=79938 op=3 DEL dn="employeeNumber=24387,ou=humans,ou=foo" As far as I can see, there is only sync activity for the MOD action, and not for the DEL action. The DEL is not synced. Marc
