Very common business requirement is to update users roles dynamically without asking them to re-login and also profile pictures.
This problem is pending the fix related to PRB1360299/KB0951799 because the photo ref which is being used to get the image from the cache will now get deleted. Just run a following code in the background script, this is a kinf of usefull feature for developers.
Refresh roles without forced log-out
GlideSecurityManager.get().setUser(gs.getUser());
Refresh GlideUser session cache
gs.getSession().loadUserByID(gs.getUser().getID());
GlideRollback usage
var rollback = new GlideRollback(); var modCount = 0; var sys_user = new GlideRecord('sys_user'); var userId = "--put the sysId here--"; if (sys_user.get(userId )) { modCount = parseInt(sys_user.sys_mod_count.toString(), 10); rollback.toVersion(sys_user, modCount - 1); gs.info(sys_user.last_name.toString()); rollback.toVersion(sys_user, modCount - 2); gs.info(sys_user.last_name.toString()); }
