Hi all, My name is Alex and I recently joined this list because I can't find some straight forward guidelines and nothing seems to work for me. Of course it is a dummy question and I know you saw it many time but I am sure that I'm missing something very very simple in fact. If you want, please help me because I am a bit lost and I don't know how to move forward. I am trying to setup an OpenLDAP server on Centos 7. This is my first time, so please take me easy :)) I will try to reproduce my steps because being my first time error may occur at any moment but I strongly want to learn OpenLDAP. My goal is to add some custom fields (atributeType) into Ldap DB. I know there can be a workaround for this, like add the data into inetOrgPerson schema but I want a new Schema, defined for what I need. Basically this schema will contain supplementary informations about students like (ID-Number, University Assigned Number, contact email, address, name after marriage, etc). Here are all steps I've done (successfully I believe): install and configure OpenLDAP from here: https://www.server-world.info/en/note?os=CentOS_7&p=openldap&f=1 ---- I've tried to create my new schema like this (I have my private IANA OID): ----------------------------------- info.schema ---- attributetype ( 1.3.6.1.4.1.49565.1.1.1 NAME 'cnp' DESC 'Cod Numeric Personal' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{32768} ) attributetype ( 1.3.6.1.4.1.49565.1.1.2 NAME 'emailContact' DESC 'Email for external user' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{32768} ) objectclass ( 1.3.6.1.4.1.49565.1.2.1 NAME 'infoVCard' DESC 'Extra Information Card' AUXILIARY ) ----------------------------------- * Moved to /tmp/slapd folder and created an info.conf file: include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/info.schema * transformed info.schema to ldif slaptest -f info.conf -F . config file testing succeeded * moved to cn=config/cn=schema and all 5 files are here: -rw-------. 1 root root 15546 Mar 31 22:15 cn={0}core.ldif -rw-------. 1 root root 11363 Mar 31 22:15 cn={1}cosine.ldif -rw-------. 1 root root 6495 Mar 31 22:15 cn={2}nis.ldif -rw-------. 1 root root 2857 Mar 31 22:15 cn={3}inetorgperson.ldif -rw-------. 1 root root 890 Mar 31 22:15 cn={4}info.ldif -------------------------------------------- * edited cn={4}info.ldif like so: -------------------------------------------- # AUTO-GENERATED FILE - DO NOT EDIT!!

How do I add data using this new schema? I've tried this: ldapuser.ldif --- dn: uid=alex,ou=People,dc=info,dc=uaic,dc=ro objectClass: inetOrgPerson objectClass: posixAccount objectClass: shadowAccount cn: Alexandru sn: Ocheana userPassword: {SSHA}BBxUpzvO93HlFEFPSkexvXA7G06UBYO4 loginShell: /bin/bash uidNumber: 2000 gidNumber: 2000 homeDirectory: /home/alex ## ------------------------- ## HERE I BELIEVE IS AN ERROR BUT WHICH IS THE CORRECT WAY TO ADD IT? ## THIS PART IS TO ADD DATA TO THAT NEW SCHEMA ## ------------------------- dn: uid=alex,ou=People,dc=info,dc=uaic,dc=ro objectClass: infoVCard cnp: myCNP emailContact: otheremail(a)gmail.com dn: cn=alex,ou=Group,dc=info,dc=uaic,dc=ro objectClass: posixGroup cn: Alex gidNumber: 2000 memberUid: alex ---- I am trying to add this to OpenLDAP like so: ldapadd -x -D cn=Manager,dc=info,dc=uaic,dc=ro -W -f ldapuser.ldif After asking for password I am getting this output: adding new entry "uid=alex,ou=People,dc=info,dc=uaic,dc=ro" adding new entry "uid=alex,ou=People,dc=info,dc=uaic,dc=ro" ldap_add: Object class violation (65) additional info: no structural object class provided My logic tells me that my infoVCard should be bound somehow to first set as inetPersonOrg (I've read about this but I don't know how to really achieve this ... I know about SUP but I am lost at this point). Can you bring some light into my head please? What I am missing? Thank you very much for your time! Regards, Alexandru Ocheana
