Tutorial Submissions We are looking for high-quality tutorials on LDAP and related subjects, at any level from introductory to advanced. Tutorial length can range from an hour to a full day. Wireless Internet access will be available if required. The purpose of the tutorials is focussed education, so they should cover established topics and best practice rather than presenting new work. Tutorials will be on Wednesday 11th November 2015. The Programme Committee has an open mind about the format of the tutorial day, but has a limited number of rooms available. Make your proposal early and we will aim to build an attractive programme for the day. Expenses Speakers get free access to the conference, including the social event.

R: Antw: Re: Elapsed Time logging

Hi, thank you for your interest. I was mistakenly sure of the field's availability. I would have liked to use the "etime" field to monitor OpenLDAP dependability through my SIEM platform, by identifying long lasting operations. Could you please give me some pointers about monitoring "operations completed" or any other useful parameter?

How to disable SSF (integrity) on GSSAPI mech?
by Osipov, Michael 21 Apr '15

21 Apr '15

Hi folks, I am binding against Active Directory with GSSAPI mech and would like to disable SASL integrity for debugging purposes with Wireshark. Unfortunately, this call fails: char *secprops = "minssf=0,maxssf=0"; rc = ldap_set_option(ld, LDAP_OPT_X_SASL_SECPROPS, secprops); with: Diagnostic message: SASL(-1): generic failure: GSSAPI Error: A required input parameter could not be read (Unknown error) Result code: -2 I am used to this with Java's SASL client where I can set SASL QOP with auth, auth-int, auth-conf. Is that not possible with OpenLDAP along with CyrusSASL? For what it is worth, I am on FreeBSD 9.3 with latest OpenLDAP and CyrusSASL from the ports tree. Regards, Michael

Elapsed Time logging
by fabymoscarella＠virgilio.it 20 Apr '15

Hi everyone, my name is Fabiano and I'm an italian IT Security professional involved in a IAM project which comprises several OpenLDAP instances. I'm using OpenLDAP 2.4.40 on a x86_64 Red Hat Enterprise Linux Server release 6.5 and my target is logging LDAP operations elapsed time. I configured logging through RSyslog but I can't see an "etime" field in my logfiles; below is a sample log row: Apr 20 17:46:56 hostname slapd[9884]: conn=1019 op=0 RESULT tag=97 err=0 text= I'm not using OLC and tried without specifying a "loglevel" parameter in my slapd.conf (default should be 256, shoulndn't it?) and later with several "loglevel" values, but no "etime" field appeared. Could you please help and tell me what am I doing wrong? Thank you in advice, Fabiano Moscarella

Structural object class rules
by dE 20 Apr '15

20 Apr '15

"An object or alias entry is characterized by precisely one structural object class superclass chain which has a single structural object class as the most subordinate object class. This structural object class is referred to as the structural object class of the entry." There's a bit of ambiguity with this "which has a single structural object class as the most subordinate object class" What do you mean by 'most subordinate'? Is it that there must be no parallel entries at the same level in the hierarchy?

Auxiliary object class practically of no use?
by dE 20 Apr '15

20 Apr '15

According to RFC 4512 An entry can belong to any subset of the set of auxiliary object classes allowed by the DIT content rule associated with the structural object class of the entry. From what I understand, this means auxiliary classes do not 'augment'; the no. of attributes which are possible in an entry must be a subset of the structural object class the entry belongs to.

Help: LDAP using alias to reference value of another attribute
by Poul Etto 17 Apr '15

17 Apr '15

Hi, As we store a lot of information in our LDAP server, we are looking to simplify and optimize our LDAP strucutre. Actually we have plenty OUs (like people and vpn shown hereunder) and lot of fields are duplicate (same fields with same content in different OUs). As this is not optimum and makes us push any change for a user into all concerned OUs, we woul like to use aliasing to avoid duplicating entries: This is an example of what a user would look like: dn: uid=1,ou=people,dc=red,dc=com objectClass: organizationalPerson objectClass: person objectClass: top objectClass: extensibleObject cn: Frank sn: Moses givenName: Frank Moses mail: frank.moses(a)red.com userPassword: {SSHA}XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX uid: 1 This is an example of what is to be found in the vpn account of the same user (we have home made schemas, so there are some special attributes): dn: uid=1,ou=vpn,dc=red,dc=com objectClass: top objectClass: openvpn objectClass: extensibleObject uid: 1 cn: Frank sn: Moses userUid: 1 vpnEnabled: TRUE mail: frank.moses(a)red.com userPassword: {SSHA}XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX As you can see fields cn, sn, mail are the same in both... We would like to change this to make our LDAP more dynamic. Therefore, we changed the vpn account to: dn: uid=1,ou=vpn,dc=red,dc=com objectClass: top objectClass: openvpn objectClass: extensibleObject objectClass: alias uid: 1 aliasedObjectName: uid=1,ou=people,dc=red,dc=com userUid: 1 vpnEnabled: TRUE But when requesting the server with ldapsearch it seems not to work, or maybe we just are missing someting...! For example when requesting the cn of the vpn user we would like to have the cn field in the "uid=1,ou=people,dc=red,dc=com" account. Our search: ldapsearch -W -D "cn=admin,dc=red,dc=com" -x -b 'uid=1,ou=vpn,dc=red,dc=com' cn Gives: # extended LDIF # # LDAPv3 # base <uid=1,ou=vpn,dc=red,dc=com> with scope subtree # filter: (objectclass=*) # requesting: cn # # 1, vpn, red.com dn: uid=1,ou=vpn,dc=red,dc=com # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 But no "cn" value returned... What are we doing wrong ? Thank you, Best regards, ZP

olcHidden breaks slapcat? possible bug in slapcat(8)?
by Igor Shmukler 17 Apr '15

17 Apr '15

Hello, I use olcHidden and set it to true in some instances. This seems to work, yet it breaks slapcat(8) as below: $ sudo slapcat -n 0 5530b282 olcRootPW: value #0: <olcRootPW> can only be set when rootdn is under suffix 5530b282 config error processing olcDatabase={2}hdb,cn=config: <olcRootPW> can only be set when rootdn is under suffix slapcat: bad configuration file! Is this a bug, or the desired behavior? Sincerely, Igor Shmukler
