ipmitool cannot access drac although all settings are correct

Dear DELL and community!

How can I set the parameter "IPMI Msg" which is shown by ipmitool as false on user 4 (ipmimon) inside the idrac CLI racadm to be true?

For user 2 (root) is was set by default on true For user 3 (monitest) I solved this by writing 

# ipmitool -I lanplus -L ADMINISTRATOR -H 153.X.X.X -U root -P password channel setaccess 1 3 ipmi=on

But i need a solution from inside the idrac CLI (racadm)

# ipmitool -I lanplus -L ADMINISTRATOR -H 153.X.X.X -U root -P password user list
ID Name Callin Link Auth IPMI Msg Channel Priv Limit
2 root true true true ADMINISTRATOR
3 monitest true false true USER
4 ipmimon true false false USER

Here some input for geeks :)

The following command is working for user 3 but not for 4

# ipmitool -I lan -L USER -H 153.X.X.X -U ipmimon -P PASSWORD sdr -vv
