In ARSystem exists since a long time a mechanism to prevent that several user can work with the same logonid (and the same license).
At the moment it saves a cookie (G-cookie) in user-browser and at the server. If the user come with a wrong cookie, the ARERR 9084 appears.
In earlier times with ARUser it saved the IP-address of the client, which worked fine.
Now with midtier there are several ways that this mechnism fails:
- User uses different browser
- user work swith private browser sessions
- user clears the browsercache
- user accesses midtier with different urls (cookie is dependent from url)
Besides the error-possibilties the whole mechanism makes no sense anymore.
Maybe it was possible to work in ARSytem with only one user in the past.
But as now the ITSM-application exists, it is not possible to do this, you would have to change the complete ITSM-application.
So please disable it
