When selecting an application for a "managed" account using the "Accounts" pref pane doesn't enable that application, the reason is often that the application developer has neglected to include sufficient information with the programme to allow the system to identify it uniquely. For example, the '
CFBundleIdentifier' may be absent in the app's "Info.plist" file. In many cases, it may be possible to modify the app to remedy the situation.
However, with a "Simple Finder" account, which in "Tiger" doesn't really block the user's ability to launch applications, an easier workaround may be simply to create a Finder "alias" for the application in the user's "home" directory (this won't work with a "Some Limits" account).
To do this, log in to the account, and use the "Finder" menu item to switch to "Full Finder". Navigate to the application you wish to add, and drag it to eg. the "Desktop" while holding down the "command" (⌘) and "option" (⌥) keys - the mouse pointer should change to a "curved arrow" symbol to indicate that an alias will be created at the destination. Then move the alias somewhere that is accessible to the user, such as their "Documents" folder.
Alternatively, the alias can be placed in the user's "~/Library" > "Managed Items" > "My Applications" folder so that it will appear in the "My Applications" folder in the "Dock". However, be aware that since the contents of that folder are generated dynamically based the applications selected in the "Accounts" pref pane (stored in '
mcx_settings' in "NetInfo"), the alias will be deleted from that folder when the user logs in unless the alias is "locked". To lock the alias after moving it, control-click its icon, choose "Get Info" from the contextual menu, and click the "Locked" checkbox under the "General" section.
