Problem

-- getting such error when tryin to connection to Interchange UI
"Error : The number of connections allowed by your product license has been exceeded"

-- getting such error when trying to connect to a B2Bi Client tool
"Invalid user name or password! Please try again"

Resolution

* the max number of sessions set in the license includes the B2Bi user interface browser, but includes also API and B2Bi client tool sessions

* you can check the maxUserSessions element in the license.xml file by selecting Help > License information on the top toolbar in the user interface

* in the license :

<!--Maximum user sessions. This limits the maximum number of users that can log in simultaneously.--><name>maxUserSessions</name><value>1</value>

* a unique user may take several sessions, so be aware of that when requesting a B2Bi license
