Hi,

thanks for the precision. The reason why I mentioned that blog entry
was because it was pointed in another blog entry explaining how use
OpenSSO with OpenLDAP :
http://blogs.oracle.com/indira/entry/using_openldap_as_user_data

See the first point of the Limitations chapter.

But the comments on the connexitor blogs are quite false: even if
OpenLDAP support some kind of persistent search with the syncprov
overlay, it is not the psearch control used by OpenSSO, so until
OpenSSO use the other control, the persistent search of OpenSSO will
not be used on an OpenLDAP instance.
