Hi,

I have been struggling to understand how to configure unique overlay and I can't understand the error message I receive.

Adding the overlay ==================

And I'm trying to add Unique Overlay as::

dn: olcOverlay={0}unique,olcDatabase={1}hdb changetype: add objectClass: olcOverlayConfig objectClass: olcUniqueConfig olcOverlay: {0}unique olcUniqueURI: ldap:///?mail?sub

that fails with error::

test-acomea:~# ldapmodify -D cn=admin,cn=config -w isi -f ,ldapvi-test-acomea-3996.ldif adding new entry "olcOverlay={0}unique,olcDatabase={1}hdb" ldap_add: Invalid syntax (21) additional info: objectClass: value #1 invalid per syntax

I can't really understand which is the syntax error, my setup is below.

Dscription of setup ===================

I have a database to which I need to add unique constraint to the 'mail' field. I loaded uniqu module in cn-config::

cn=module{0},cn=config objectClass: olcModuleList cn: module{0} olcModulePath: /usr/lib/ldap olcModuleLoad: {0}back_hdb olcModuleLoad: {1}unique

and I have a db defined as::

test-acomea:~# ldapsearch -xLLL -D cn=admin,cn=config -b cn=config -W olcSuffix=dc=acomea,dc=it dn: olcDatabase={1}hdb,cn=config objectClass: olcDatabaseConfig objectClass: olcHdbConfig olcDatabase: {1}hdb olcDbDirectory: /var/lib/ldap olcSuffix: dc=acomea,dc=it ...

Thanks in advance sandro *:-)

PS: Any pointer to examples is very appreciated
