I'm upgrading from openldap 2.0.27 to openldap 2.1.22 on GNU/Linux Debian Woody
on x86. slapd now refuse to start when i try to use a schema subtyping referral
objectClass :

reading config file /usr/local/etc/openldap/schema/test.schema
line 4 (objectClass ( 1.3.6.1.4.1.7135.1.3.201.1.4.1.25        NAME
'testObjectClass'        SUP referral STRUCTURAL        MUST ref ))
/usr/local/etc/openldap/schema/test.schema: line 4: user-defined ObjectClass has
inappropriate SUPerior: "( 1.3.6.1.4.1.7135.1.3.201.1.4.1.25        NAME
'testObjectClass'        SUP referral STRUCTURAL        MUST ref )"

Here is the schema file : /usr/local/etc/openldap/schema/test.schema

objectClass ( 1.3.6.1.4.1.7135.1.3.201.1.4.1.25
        NAME 'testObjectClass'
