Hello,
is it possible define a unique constraint across attributes? We have a mail
field and a mailAlias field and would like to assure that if a mail address
exists either in mail or mailAlias it cannot be added again to either
field, meaning mail addresses are unique in the complete tree.
We are using OpenLDAP 2.4 and currently we use the following LDIF to load
the unique module and assure that the mail attribute is unique:
dn: cn=module,cn=config
cn: module
objectclass: olcModuleList
objectclass: top
olcmoduleload: unique
olcmodulepath: /usr/lib/ldap
dn: olcOverlay=unique,olcDatabase={1}hdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcUniqueConfig
olcOverlay: {0}unique
olcUniqueAttribute: mail
Which LDIF would I use to assure uniqueness across mail and mailAlias?
Cheers,
Stefan Schmidt
