Look up users in a .db database and verify their password against
what is contained in that database. The database will have been
created using db_load.
debug write a message to syslog indicating success or
db=[path] use the [path] database for performing lookup. There
is no default; the module will return PAM_IGNORE if
no database is provided. Some versions of DB will
automatically append ".db" to whatever pathname you
crypt=[mode] indicates whether encrypted or plaintext passwords
are stored in the database. If [mode] is "crypt",
passwords should be stored in the database in
crypt(3) form. If [mode] is "none" or any other
value, passwords should be stored in the database in
icase make the password verification to be case insensitive
(ie when working with registration numbers and such)
only works with plaintext password storage.
dump dump all the entries in the database to the log (eek,
don't do this by default!)
use_authtok use the authentication token previously obtained by
another module that did the conversation with the
application. If this token can not be obtained then
the module will try to converse again. This option can
be used for stacking different modules that need to
deal with the authentication tokens.
unknown_ok do not return error when checking for a user that is
not in the database. This can be used to stack more
than one pam_userdb module that will check a
username/password pair in more than a database.
key_only the username and password are concatenated together
in the database hash as 'username-password' with a
random value. if the concatenation of the username and
password with a dash in the middle returns any result,
the user is valid. this is useful in cases where
the username may not be unique but the username and
password pair are.
