Hi Dave,
Indeed, the problem would seem to happen when the cache is full (at least it is solved when I have increased the kernel parameter MaxSize).
"But you should always be able to get it back out of the database": this means that I must explicitly query he table sec_session_properties (in order to avoid the error -lost values- that I get using ad_get_client_property)?
Thanks a lot for your help!
Jorge.
