Migration process in detail
by Rodrigo Coutinho 11 Aug '14

11 Aug '14

Hi, in a near future I will need to migrate from Oracle OID to Openldap. Could you please share more details of your migration process, the approach taken, the problems you faced and how did you resolved them. Right now I can't see how can I migrate the encripted user passwords. Is it possible ? I would appreciate any information you could provide.

Why cannot run slapadd -l backup.ldif which requires deprecated lsapd.conf?
by jupiter 09 Aug '14

09 Aug '14

Hi, I am running openldap version 2.4.23 on CentOS 6.5, there is no slapd.conf, according to the document it is deprecated. But when I run slapadd, it got an error. # slapadd -v -l /root/backup.ldif could not stat config file "/etc/openldap/slapd.conf": No such file or directory (2) slapadd: bad configuration file! Now I am confused, if the slapd.conf is deprecated why the slapadd sdepends on it? How can I generate the slapd.conf, or copy a template of slpad.conf? Thank you and appreciate your advice - j

Hi All Just getting my feet wet with LMDB. Is it possible for multiple threads write into LMDB concurrently? Or should writes be serialized to LMDB? Thanks Bill

Help for encrypted password with Blowfish
by Franck Goirand 08 Aug '14

08 Aug '14

Hello, I have a text file containing users and their password encrypted blowfish. This password is in the form $ 2a $ 08 $ hNbsbhDlbaogpYL/2yeCkuxKPPGKcluKb5rk16R0Nwi/34eGVi8r2 I need to create a script for insert the users in a directory via ldap ldif file. For the password, I use the userPassword instruction. If I put the password as contained in the file, it does not work. My issue are: - Is it possible to type in a password (encrypted in blowfish) as such ldap directory? - What syntax i need to use to tag the userPassword ({crypt} password ...)? - Should i perform a specific configuration for the slapd.conf file for the pam authentication engine (pam-ldap is it sufficient)? I worked on the crypt library, pam_ldap, slapcat ... without success Any ideas would be welcome, Best regards Franck ps: before passwords were MD5 and I never encountered any problems.

by Katherine Faella 07 Aug '14

I am running openldap on Redhat 6 at 2.4.23. I am using cn=config. I have a schema called uri was added during the initial setup of this server a few years ago. In this schema I have an dn: cn={12}uri,cn=schema,cn=config objectClass: olcSchemaConfig cn: {12}uri olcAttributeTypes: {0}( 1.3.6.1.4.1.14092.2.1.1 NAME 'uriid' EQUALITY caseIgno reMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{256} ) olcAttributeTypes: {1}( 1.3.6.1.4.1.14092.2.1.2 NAME 'dept' EQUALITY caseIgnor eMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{ 256} ) .... *olcObjectClasses: {7}( 1.3.6.1.4.1.14092.2.2.8 NAME 'URIEducmanager' DESC 'URI** ** Educmanager' STRUCTURAL MAY ( uid $ userPassword $ employeeNumber $ cn $ sn $** ** givenname $ telephoneNumber $ dc ) )* olcObjectClasses: {8}( 1.3.6.1.4.1.14092.2.2.9 NAME 'URIEdusakaiperson' DESC ' URIEdusakaiperson' STRUCTURAL MUST ( URIEduemplid $ URIEduecampusid $ URIEdus n $ URIEdustatus $ userPassword ) MAY ( mail $ URIEdugn ) ) I need to update the URIEducmanager objectclass to include the mail object so it will be: olcObjectClasses: {7}( 1.3.6.1.4.1.14092.2.2.8 NAME 'URIEducmanager' DESC 'URI Educmanager' STRUCTURAL MAY ( uid $ userPassword $ employeeNumber $ cn $ sn $ givenname $ mail $ telephoneNumber $ dc ) ) I have tried many combinations the last of which is ldapmodify -D "cn=admin,cn=config" -x -W -f /root/ldapscripts/updatecmanager.ldif -v -H ldap://locumtenens.uri.edu where updatecmanager.ldif contains: dn: cn={12}uri,cn=schema,cn=config changetype: modify delete: objectclass objectclass: ( 1.3.6.1.4.1.14092.2.2.8 NAME 'URIEducmanager' DESC 'URIEducmanager' STRUCTURAL MAY ( uid $ userPassword $ employeeNumber $ cn $ sn $givenname $ telephoneNumber $ dc ) ) - add: objectclass objectclass: ( 1.3.6.1.4.1.14092.2.2.8 NAME 'URIEducmanager' DESC 'URIEducmanager' SUP top AUXILIARY STRUCTURAL MAY ( uid $ userPassword $ employeeNumber $ cn $ sn $givenname $ mail $ telephoneNumber $ dc ) ) My run looks like ldapmodify -D "cn=admin,cn=config" -x -W -f /root/ldapscripts/updatecmanager.ldif -v -H ldap://locumtenens.uri.edu ldap_initialize( ldap://locumtenens.uri.edu:389/??base ) Enter LDAP Password: delete objectclass: ( 1.3.6.1.4.1.14092.2.2.8 NAME 'URIEducmanager'DESC 'URIEducmanager'STRUCTURAL MAY ( uid $ userPassword $ employeeNumber $cn $ sn $givenname $ telephoneNumber $ dc ) ) add objectclass: ( 1.3.6.1.4.1.14092.2.2.8 NAME 'URIEducmanager'DESC 'URIEducmanager' SUP top AUXILIARYSTRUCTURAL MAY ( uid $ userPassword $ employeeNumber $cn $ sn $givenname $ mail $ telephoneNumber $ dc ) ) modifying entry "cn={12}uri,cn=schema,cn=config" ldap_modify: Invalid syntax (21) additional info: objectclass: value #0 invalid per syntax I have checked for extra blanks on the line, I have tried it with replace instead of delete and add.

ACL for object creation in subtree with specific attributes and object classes
by Simeon Ott 06 Aug '14

06 Aug '14

Hello, I'd like to refine my permission set of my openldap installation. The tree structure is: dc=mydomain - cn=admin (ldap admin) - ou=domains (customer domains) - ou=example1.com - cn=user1 - cn=user2 - cn=postmaster - ou=example2.com - cn=user1 - cn=user2 - cn=postmaster The user postmaster is able to change specific attributes of objects in its own "domain" (one level up). The current ACLs are defined as: access to dn.regex="^(.+,)?ou=(.+),ou=domains,dc=mydomain$" attrs=userPassword by dn.base="cn=admin,dc=mydomain" write by self write by dn.base,expand="cn=postmaster,ou=$2,ou=domains,dc=mydomain" write by anonymous auth by * none access to attrs=userPassword by dn.base="cn=admin,dc=mydomain" write by self write by anonymous auth by * none access to dn.regex="^(.+,)?ou=(.+),ou=domains,dc=mydomain$" attrs=sn,description,vacationActive,vacationInfo,vacationForward,displayName,givenName,homePhone,homePostalAddress,initials,mobile,postalAddress,postalCode,l,telephoneNumber,title by self write by dn.base,expand="cn=postmaster,ou=$2,ou=domains,dc=mydomain" write by * read access to dn.regex="^(.+,)?ou=(.+),ou=domains,dc=mydomain$" by dn.base,expand="cn=postmaster,ou=$2,ou=domains,dc=mydomain" write by * read access to * by dn.base="cn=admin,dc=mydomain" write by * read ACL rule 4 allows the postmaster to add objects to it's "domain" without any restrictions. How can i restrict the object creation to specific object classes and attributes? Let's say postmaster should only be able to add objects like the following: dn: cn=user3,ou=example2.com,ou=domains,dc=mydomain objectClass: CourierMailAccount objectClass: inetOrgPerson objectClass: top objectClass: Vacation cn: user3 homeDirectory: user3/example2.com/ mail: user.3(a)exampl2.com sn: User3 vacationActive: TRUE gidNumber: 5000 smtpRelayFlag: 1 uidNumber: 5000 userPassword:: <crypted password> vacationInfo:: <binary data> I didn't find such an approach in Faq-O-Matic nor the manuals Thanks in advance for any advice

Hi, I have openldap 2.4.36 installed using mdb backend on Solaris 10. I am using this database for a while and suddenly I started getting core dumps while trying to add any data to database.
