200 Chapter 11 Solving Problems
Users Relying on a Password Server Can’t Log In
If your network has a server with Mac OS X Server version 10.2, it could be configured
to get authentication from an Open Directory Password Server hosted by another
server. If the Password Server’s computer becomes disconnected from your network,
for example because you unplug the cable from the computer’s Ethernet port, users
whose passwords are validated using the Password Server can’t log in because its IP
address isn’t accessible.
Users can log in to Mac OS X Server if you reconnect the Password Server’s computer to
the network. Alternatively, while the Password Server’s computer is offline, users can
log in with user accounts whose password type is crypt password or shadow password.
Users Can’t Log In With Accounts in a Shared Directory Domain
Users can’t log in using accounts in a shared directory domain if the server hosting the
directory isn’t accessible. A server may become inaccessible due to a problem with the
network, the server software, or the server hardware. Problems with the server
hardware or software affect users trying to log in to Mac OS X computers and users
trying to log in to the Windows domain of a Mac OS X Server PDC. Network problems
may affect some users but not others, depending on where the network problem is.
Users with mobile user accounts can still log in to the Mac OS X computers they used
previously. And users affected by these problems can log in by using a local user
account defined on the computer, such as the user account created during initial setup
after installing Mac OS X.
Users Can’t Access Their Home Directories
Make sure that users have access to the share point in which their home directories are
located and to their home directories. Users need Read access to the share point and
Read & Write access to their home directories.
Users Can’t Change Their Passwords
Users who have accounts in the server’s LDAP directory with a password type of “crypt
password” cannot change their passwords after logging in from a client computer with
Mac OS X version 10.3. These users can change their passwords if you use Workgroup
Manager’s Advanced pane to change their accounts’ User Password Type setting to
Open Directory. When you make this change, you must also enter a new password.
Then you should instruct users to log in using this new password and change it on the
Accounts pane of System Preferences.
