- From shadow-15.0.0 all references to cracklib were removed from shadow. Apparently some functions were no longer accessible and the shadow team decided to remove cracklib references completely. This was not mentioned in the changelkog for 15.0.0 - This resulkts in gettinbg the message configuration error - unknown item 'CRACKKLIB_DICTPATH' ( notify administrator ) when logging in to the console. - The login to the console occurs successfully so the message is only a warning that cracklib is no longer used. - IPfire does not use cracklkib anyway so this patch removes the section referring to cracklib from the login.defs configuration file.
