User identification
From OpenKM Documentation
In this space of the desktop screen the user identification who is connected in this session is identified.
In the event of detecting some user with AdminRole as the user, the identifier will appear in another colour, with the purpose of indicating that operations are being carried out under a “super-user” without any restrictions of document access.
Changes from version 3.0 to 4.0
In OpenKM version 3.0 and olders, there was only one username with administrator grants called okmAdmin.
