Problem using the modifyTimestamp Attribute

["Mike" <sigtraq@fastmail.fm>]

Hi,

I believe I have a problem with the built-in attribute modifyTimestamp.

When I add the attribute to an objectclass, it will complain to me that
"user-defined ObjectClass has inappropriate SUPerior"

Through divide and conquer, I realised that modifyTimestamp attribute is
the one that gives me the error.

What am I missing here?


-----------------------------------------------------------------
Object Class
-----------------------------------------------------------------
objectclass ( 1.3.6.1.4.1.3401.8.2.25
        NAME 'pgpUserID' AUXILIARY
        MUST  ( objectclass $ pgpCertID $ pgpDisabled $ pgpKeyID $
        pgpKeyType $ pgpUserID $ pgpKeyCreateTime $ pgpSignerID $
        pgpRevoked $ pgpKeySize $ pgpKeyExpireTime $ modifyTimestamp )
        MAY  ( pgpSubKeyID ) )


----------------------------------------------------------------
Restart the ldap server after inserting the modifyTimestamp
----------------------------------------------------------------
