Mac OS X v10.5.7: Cannot log in on managed client

After updating to Mac OS X v10.5.7, a user may not be able to log in to a managed client workstation. On startup, or after entering the user name and password, the user may be prompted for an administrator name and password, but nothing can be entered.

This issue can occur on PowerPC-based Macs if the file /etc/authorization is not updated correctly when installing the Mac OS X v10.5.7 Update.

Download and install the Mac OS X v10.5.8 Update manually or via Software Update.

To resolve this issue without updating to Mac OS X v10.5.8, copy the file /etc/authorization from an unaffected computer to the affected computer, then restart.

Note: When copying the file make sure that it has the correct permissions set at the destination. If you enter the following command in a Terminal window:

ls -l /etc/authorization

...the results should look like:

-rw-r--r--  1 root  wheel  22017 May 12 22:29 /etc/authorization
