Garry, You can create and put in an Role your company for your user needs in LSF9 security. Check the Lawson document "Lawson Administration - Resources and Security 9.0". Great for understanding how many things in LSF9 work. There are some pre-created roles and groups for you already. Every company is different so it depends on the Roles and Groups your company has decided upon. If you are using LSF9 security (LS Security turned on, and not using LAUA security), then yes, if you want users to "securily" access Lawson, they would need to be put in Groups/Roles. 2. No, you don't need to create rules for invoked programs, unless you very specifically need to. Think of how messy it could get if you needed to secure and write a rule for every single invoked program for a PO20, or HR11 for example. Roger Posted By Garry Ferwerda on 01/28/2009 12:56 PM Hi: I have a couple of questions about implementing Lawson securtiy: 1) I have not found any documentation or seen any discussion on what role the user group that is entered on the security tab of laconfig has if LS security is being used. Do all Lawson users still need to be a member of this group if they are using LS security and not accessing the LID command line? 2) Do rules have to be written for the invoke programs (HPPV, HACV for example) if they are not going to be accessed directly, but only accessed via a calling program? Thanks
