Some Cross Platform Questions and Answers
Some Questions and Answers

1) Can OS X authenticate against NT domains?

Depends on what they mean by authenticate. No, the login window won't make calls to the NT domain controller, but when they attach to smb
shares, they can authenticate with users in the NT domain.

2) What encryption is used for local passwords?

According to the Open Directory Admin Guide, (http://www.apple.com/server/documentation/) a shadow password's primary hash function is SHA-1. In addition, NT and LAN Manager hashes are stored in the shadow password file for backwards compatibility with Windows SMB file and Print services. The NT and LAN Manager hashes can be used for Windows personal file sharing from a Mac OS X computer and can also be used to authenticate Windows file and print services provided by Mac OS X Server.

3) Can OS X restore from an OS X dump?

Standard BSD commands like dump and restore don't catch resource forks.
You can't dump to a tape, because of the way Mac OS X handles device files (no /dev/tape).
