Non-personal mail accounts

[Nick Milas <nick@eurobjects.com>]

Hello,

We are storing user accounts in OpenLDAP. Main classes used are:

   objectClass: top
   objectClass: person
   objectClass: organizationalPerson
   objectClass: inetOrgPerson
   objectClass: eduPerson

User email address(es) is (are) stored in the "mail" attribute and are 
also used by Postfix (which uses virtual accounts based on LDAP).

I would like to define some email accounts (with associated email 
addresses) which do NOT belong to a particular user; so, in these 
accounts a mail attribute would not be associated (both conceptually and 
practically) with a person objectClass.

Is there a suggestion on which existing objectClass(es) (and associated 
schemas, if applicable) should we use for such use? I thought of 
"account" (defined in cosine.schema), but it does not accept a mail 
attribute. The idea would be to use something like an extended "account" 
objectClass, (or "account" itself, with some additional auxiliary class 
to define an email address) together with simpleSecurityObject to allow 
definition of a password.

Any experiences, suggestions will be appreciated.

Thanks,
Nick
