Hello!
I use OpenLDAP wuth MySQL backend.
I added even memberOf and it's all ok on db and I see the correct members (on groups) and memberOf (on people).

But I have a problem: I can't search if a user is member of a group.
filter:
(&
    (objectClass=inetOrgPerson)
    (uid=username)
    (memberOf=cn=test,ou=group,dc=organization,dc=it)
)

on the log I read:
get_ava: illegal value for attributeType memberOf

Can someone help me?

Thanks,
Arianna
