Can anybody please suggest me, if we can restric the access to a user to the webconsole of a ovow(7.5) manager?
If yes, Can you pleas let me know?
You can set this using UserRoles. Basically users who are members of HP-OVE-ADMINS or HP-OVE-OPERATORS or Local Administrators group (of OVOW 7.5 server) will have access to Web Console. An user who is member of HP-OVE-ADMINS will have full access to OMW and you cannot restrict anything. An user who is member of HP-OVE-OPERATORS will have access based on the UserRole that you define for them.
Web Console and OVOW MMC COnsole follow same rules as far as User Access rights is concerned.
