Subject: [PATCH 60/91] Do not allow multiple sessions when nr_sessions=1
|
||
|
|
|
||
|
|
If a request is made to login to a target, creating
|
||
|
|
a session, then another request is submitted so quickly
|
||
|
|
that the first one has not completed, both requests
|
||
|
|
can succeed, despite having nr_sessions=1 configured.
|
||
|
|
|
||
|
|
Only allow multiple login requests if nr_sessions is
|
||
|
|
greater than 1.
