OpenDJ: Editing 'gecos' schema syntax causes 'posixAccount' to be removed and creates a duplicate OID


OpenDJ 4.4.11
RHEL 7.9

Currently, our production LDAP servers are on OpenDJ 4.4.11. We did not have a pre-prod environment so I decided to make one for upgrade testing. While setting up the server to match production, I encounter schema issues.

I need to update the 'gecos' attributeType that comes with an OpenDJ install. We have users who need the syntax 1.3.6.1.4.1.1466.115.121.1.15 for accents, etc. I apply the following:

/opt/opendj/bin/ldapmodify --port 389 --bindDn cn=manager --bindPassword $CNMAN 
/opt/opendj/ldif/mod_gecos.ldif

which contains:

dn: cn=schema
changetype: modify
delete: attributeTypes
attributeTypes: ( 1.3.6.1.1.1.1.2 NAME 'gecos' DESC 'The GECOS field; the common name' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE X-ORIGIN '04-rfc2307bis.ldif' )
-
add: attributeTypes
attributeTypes: ( 1.3.6.1.1.1.1.2 NAME 'gecos' DESC 'The GECOS field; the common name' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE X-ORIGIN 'draft-howard-rfc2307bis' X-SCHEMA-FILE '99-user.ldif' )

This completes successfully, but then after several minutes OR a service restart, /opt/opendj/bin/stop-ds --restart I get the following:

category=CONFIG severity=WARNING msgID=761 msg=The config schema file '04-rfc2307bis.ldif' generated warning when trying to update schema with its content: [Unable to register attribute type name with the server schema because its OID 2.5.4.41 conflicts with the OID of an existing attribute type name, Validation of object class definition ( 1.3.6.1.1.1.2.0 NAME 'posixAccount' DESC 'Abstraction of an account with POSIX attributes' SUP top AUXILIARY MUST ( cn $ uid $ uidNumber $ gidNumber $ homeDirectory ) MAY ( authPassword $ userPassword $ loginShell $ gecos $ description ) X-ORIGIN 'draft-howard-rfc2307bis' X-SCHEMA-FILE '04-rfc2307bis.ldif' ) failed and will be removed from the schema: The object class "posixAccount" specifies the optional attribute type "gecos" which is not defined in the schema]

What could I be doing wrong? Prior to the gecos update, service restarts never show the above warnings and error messages.


Solution

  • When you do the modification of the schema, you store the result in the 99-user.ldif file, which will be the last one to load.

    When loading the 04-rfc2307bis.ldif file, the "gecos" attribute is not yet defined and this invalidates the "posixAccount" definition.

    You should make sure the definition of "gecos" is stored in the same schema file.
