Non-Windows: Case-insensitive permission check of SSO user

The described configuration procedure (non-Windows) yields the sso_permissions.xml file implementing a case-sensitive permission check; this is desired when all involved System Login / SSO User pairs consist of identical strings. However, if the case is different for one or more application users, the permission check must be case-insensitive. To achieve this in the sso_permissions.xml file, specify this information:

<sso_user name="#"/>

instead of

<sso_user name="+"/>
