ADDING OBJECT CLASS

For my Users, currently utilizing the following:

ObjectClass: account (structural) objectClass: posixAccount (auxiliary) objectClass: pwdPolicy (auxiliary) objectClass: shadowAccount (auxiliary) objectClass: top (abstract) cn: gidNumber: homeDirectory: pwdAttribute: uid: uidNumber: gecos: loginShell: pwdAllowUserChange: pwdMinLength: pwdMustChange: shadowLastChange: userPassword:

I would like to add and objectClass(es) so that I can add, emailAddress, employee number. Can someone refresh my memory on what I need (objectClasses)?

Thanks,
