7the repositories configured on a stock system.

10.. NOTE::
11
12    The Cyrus project does not support running any versions of the Cyrus
13    IMAP software older than the version of the software shipped
14    with the operating system itself.
15
16To install the version of Cyrus IMAP that comes with the operating
17system, issue the following command:
18
19.. parsed-literal::
20
21    # :command:`apt-get install cyrus-imapd cyrus-sasl cyrus-sasl-plain`
22
23If you want xapian, you'll need to :ref:`build all of Cyrus yourself <compiling>`.
24
25Next, set a password for the default administrative user ``cyrus``:
26
27.. parsed-literal::
28
29    # :command:`passwd cyrus`
30    Changing password for user cyrus.
31    New password:
32    Retype new password:
33    passwd: all authentication tokens updated successfully.
34
35Start and configure to start when the system boots, the
36:manpage:`saslauthd` service:
37
38.. parsed-literal::
39
40    # :command:`service saslauthd start`
41    Starting saslauthd:                                        [  OK  ]
42    # :command:`chkconfig saslauthd on`
43
44You should at this moment be able to authenticate against
45:manpage:`saslauthd`:
46
47.. parsed-literal::
48
49    # :command:`testsaslauthd -u cyrus -p YOUR-PASSWORD`
50
51You should get an ``0: OK "Success."`` message.
52
53.. todo::
54    If this does not succeed, see ref:`sasl-troubleshooting-saslauthd`.
55
56Start the service, and ensure the service starts up when the system
57boots:
58
59.. parsed-literal::
60
61    # :command:`service cyrus-imapd start`
62    # :command:`chkconfig cyrus-imapd on`
63
64You should now be able to login as the ``cyrus`` user, which is
65configured by default as an administrator for Cyrus IMAP:
66
67.. parsed-literal::
68
69    # :command:`imtest -t "" -u cyrus -a cyrus localhost`
