I was facing this strange error "dn: attribute type undefined" while I am trying to delete attributes from the LDAP. My ldif file has two attributes to be deleted.
cat /tmp/modifyattr.ldif
dn: fsFgId=Child2, fsFgId=Child1, fsClsId=Root
changetype: modify
delete: fsListeningHost
dn: fsFgId=Child2, fsFgId=Child1, fsClsId=Root
changetype: modify
delete: fsPort
When ldapmodify command is executed...
