Hi,

I think there is a bug / limitation inside VLV implementation : it can not handle multiple search operation on a single connection. The first operation succeeds and next operations fail with the following message :

LDAP: error code 51 - Other sort requests already in progress

But I think this issue is more global. This implementation seems to be able to only handle a single VLV context per connection.

Correct, that is by design.

If I am right, this is related with the indexing method of sort_conns structure which seems to be based only on the connection id. I suggest to implement a double indexing array by connection id / VLV context id.

I have no interest in extending this. It would require much more overhead to protect the slapd from getting overloaded by too many such requests.
