[global] encrypt passwords = yes smb passwd file (Web site construction)
[global] encrypt passwords = yes smb passwd file = /usr/local/samba/private/smbpasswd unix password sync = yes passwd program = changepass %u Note that this program will be called as the rootuser when the unixpasswordsyncoption is set to yes. This is because Samba does not necessarily have the plaintext old password of the user. The harder option to configure is passwdchat. The passwdchatoption works like a Unix chat script. It specifies a series of strings to send as well as responses to expect from the program specified by the passwdprogramoption. For example, this is what the default passwdchat looks like. The delimiters are the spaces between each groupings of characters: passwd chat = *old*password* %o\n *new*password* %n\n *new*password* %n\n *changed* The first grouping represents a response expected from the password-changing program. Note that it can contain wildcards (*), which help to generalize the chat programs to be able to handle a variety of similar outputs. Here, *old*password*indicates that Samba is expecting any line from the password program containing the letters oldfollowed by the letters password, without regard for what comes on either side or between them. Once instructed to, Samba will wait indefinitely for such a match. Is Samba does not receive the expected response, the password will fail. The second grouping indicates what Samba should send back once the data in the first grouping has been matched. In this case, you see %o\n. This response is actually two items: the variable %orepresents the old password, while the \nis a newline character. So, in effect, this will “type” the old password into the standard input of the password changing program, and then “press” Enter. Following that is another response grouping, followed by data that will be sent back to the password changing program. (In fact, this response/send pattern continues indefinitely in any standard Unix chat script.) The script continues until the final pattern is matched.[2] [2] This may not work under Red Hat Linux, as the password program typically responds “All authentication tokens updated successfully,” instead of “Password changed.” We provide a fix for this later in this section. You can help match the response strings sent from the password program with the characters listed in Table 6.6. In addition, you can use the characters listed in Table 6.7 to help formulate your response. Table 6.6: Password Chat Response Characters Character Definition * Zero or more occurrences of any character. ” ” Allows you to include matching strings that contain spaces. Asterisks are still considered wildcards even inside of quotes, and you can represent a null response with empty quotes. 201
