I am in the process of migrating my OpenLdap 2.3 system to a new OpenLdap 2.4 system but something is not working right for the import(slapadd) to the new system. There are 35,895 objects defined in the LDIF generated by slapcat. RPM: openldap-servers-2.4.44-21.el7_6.x86_64 Example: Importing the following object by slapadd: dn: cn=demokag,ou=Groups,dc=somewhere,dc=org *cn*: demokag *description*: KAG Demo *owner*: cn=manager,dc=somewhere,dc=org objectClass: top objectClass: groupOfUniqueNames *uniqueMember*: uid=sombody,ou=People,dc=somewhere,dc=org *uniqueMember*: uid=somebodyelse,ou=People,dc=somewhere,dc=org structuralObjectClass: groupOfUniqueNames entryUUID: 78450864-a24e-1030-9086-8baf95aed3fc creatorsName: cn=Manager,dc=somewhere,dc=org createTimestamp: 20111113142106Z entryCSN: 20121116140519Z#000000#00#000000 modifiersName: cn=Manager,dc=somewhere,dc=org modifyTimestamp: 20121116140519Z Produces this object: dn: cn=demokag,ou=groups,dc=somewhere,dc=org *givenName*: demokag *owner*: KAG Demo *uniqueMember*: cn=manager,dc=somewhere,dc=org objectClass: top objectClass: groupOfUniqueNames *gidNumber*: uid=somebody,ou=People,dc=somewhere,dc=org *gidNumber*: uid=somebodyelse,ou=People,dc=somewhere,dc=org structuralObjectClass: groupOfUniqueNames entryUUID: 78450864-a24e-1030-9086-8baf95aed3fc creatorsName: cn=Manager,dc=somewhere,dc=org createTimestamp: 20111113142106Z entryCSN: 20121116140519Z#000000#00#000000 modifiersName: cn=Manager,dc=somewhere,dc=org modifyTimestamp: 20121116140519Z 1. I bolded the impacted attributes. 2. I am unable to do ldapsearch for this object. I believe this is because the cn is being replaced with givenName. 3. Spot checking it appears this is happening to all of the objects under the groups OU. Maybe other object types are bad too. I do not know yet. I have been beating my head on this for several days.Any help would be appreciated.
