In EOS, there is a possibility to log the behaviour of users and resources. For every user login/logout and every action on a resource, a record is stored in an Access-database.
The database-size can grow fast. Follow up the logdatabase and clean the tables from time to time.
To enable the logging, you can do the following:
OrbitServer= Version=3 AdministratorGroup= ...
OrbitServer= Version=3 LoginLogConfiguration= Enabled=true DataSourceName=logdatabase TableName=logins AccessLogConfiguration= Enabled=true DataSourceName=logdatabase TableName=datasets DataSetMasks=*multi*,*cadmap* AdministratorGroup= ...
