When troubleshooting user desktop issues, it may be necessary to reset the password. When doing so, you will usually want to force the user to change his or her password as soon as you re done with your work. The best way to do this is to force a password change at next login for that specific user. To do this, open Workgroup Manager and connect to your Open Directory server, finding the user account in question. With the user selected, password policies can be found by clicking on the Options button under the Advanced tab for the user. Here, you can set numerous peruser password policies. As mentioned in Figure 7-26 s warning, settings set here can override global policies.

There are a few caveats to forcing a user to change their password this setting. First and foremost, not all network services in OS X support the ability to force a password change. Notably, the services that do support this are limited in 10.5 and 10.6 to loginwindow, the account system preference pane, an AFP authentication, Kerberos, and the web password change portal introduced in 10.6. For other unsupported services, such as ssh, iCal, mail, and wiki services, when a user has a forced password change active, then these services will simply fail authentication. As such, it is important that you properly communicate with your users both that you reset their password, as well as make sure that they are familiar with the procedure to reset it. If your email system utilizes Open Directory for authentication, setting this will lock them out of their email and constrain your ability to communicate with them.

A relatively new but exciting JSR is CHAPI, the Content Handler API. CHAPI finally provides a good generic way of allowing different apps on the same phone to communicate with one another. Certain apps can register as content handlers for particular MIME or URL types. When other apps make a request to handle that type of content, the device AMS (Application Management System) will invoke the registered app and allow it to service the request. When complete, the results are passed to the requesting app. Figure 3-10 illustrates the basic sequence that takes place when requesting content handling through CHAPI.

In Figure 2-9, the cls.method function references an implementation that contains two functions, overloadedFunc and embeddedFunc. The embeddedFunc variable is a reference to the overloaded function that will be called if the number of calling arguments equals the number of parameters of the overloaded function. If the parameter counts are not equal, then embeddedFunc is called. Figure 2-9 shows a chaining of overloaded methods, but uses the same architecture as described in Recipes 2-16 and 2-17. For example, it is possible to have a delegate call an overloaded method, which then calls a proxy.

Managing keychains will become a clear and present issue in the life of a Mac administrator. Keychains in OS X are encrypted files, which are used to store various sensitive information. Keychains are a system-wide framework that allows applications to utilize, providing a single universal method for password management. Each user has a default login keychain, which is automatically unlocked at login, provided the password provided at login is the same as that configured for the keychain. The login

Note: If you have programmed for the Android platform, this may sound familiar. A BlackBerry CHAPI request is very similar to an Android Intent. RIM has embraced the CHAPI system for several forms of inter-app communication. Because the native media application is already registered as a CHAPI handler, all you need to do is make a request to handle the type of audio, as shown in the code that follows.
