New objectClass

How can i add mailacceptinggeneralid and maildrop attirbutes to use postfix with openldap ? I tried to adding a schema like (into /etc/ldap/schema) # # postfix.schema - basic attributes based on default queries # postfix will make for alias and virtual account lookups # I don't think there is an official postfix schema out there, # but if there is, this most certainly is not it. # # leah(a)frauerpower.com # # mailacceptinguser and mailAccount added by Barrie Bremner < bjb(a)netcraft.com&gt; # attributetype ( 1.3.6.1.4.1.25260.1.000 NAME 'mailacceptinggeneralid' DESC 'Defines an address that we accept mail for' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.25260.1.001 NAME 'maildrop' DESC 'Defines the address mail goes to' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.25260.1.002 NAME 'mailacceptinguser' DESC 'Defines if this user accepts mail' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) objectClass ( 1.3.6.1.4.1.25260.1.1.100 NAME 'virtualaccount' DESC 'Holds mail info for a virtual account' STRUCTURAL MUST ( owner $ mailacceptinggeneralid $ maildrop $ cn ) ) objectClass ( 1.3.6.1.4.1.25260.1.1.101 NAME 'maillist' DESC 'Virtual account for holding mailing list info' STRUCTURAL MUST ( mailacceptinggeneralid $ maildrop $ cn ) ) objectClass ( 1.3.6.1.4.1.25260.1.1.102 NAME 'mailAccount' DESC 'Email account details' AUXILIARY MUST ( mailacceptinguser $ maildrop $ cn ) MAY ( mailacceptinggeneralid ) ) and add a line into /usr/share/slapd/slapd.conf " include /etc/ldap/schema/inetorgperson.schema" But i am geting ldap_add: Invalid syntax (21) additional info: objectClass: value #3 invalid per syntax when i try to add an object objectClass:mailAccount Where am i wrong?
