pam_userdb
PAM_USERDB(8) Linux-PAM Manual PAM_USERDB(8)
NAME
pam_userdb - PAM module to authenticate against a db database
SYNOPSIS
pam_userdb.so db=/path/database [debug] [crypt=[crypt|none]] [icase] [dump] [try_first_pass] [use_first_pass] [unknown_ok] [key_only]
DESCRIPTION
The pam_userdb module is used to verify a username/password pair against values stored in a Berkeley DB database. The database is indexed
by the username, and the data fields corresponding to the username keys are the passwords.
OPTIONS
crypt=[crypt|none]
Indicates whether encrypted or plaintext passwords are stored in the database. If it is crypt, passwords should be stored in the
database in crypt(3) form. If none is selected, passwords should be stored in the database as plaintext.
db=/path/database
Use the /path/database database for performing lookup. There is no default; the module will return PAM_IGNORE if no database is
provided.
debug
Print debug information.
dump
Dump all the entries in the database to the log. Don't do this by default!
icase
Make the password verification to be case insensitive (ie when working with registration numbers and such). Only works with plaintext
password storage.
try_first_pass
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. This option can be used for stacking different modules that need to deal with the
authentication tokens.
use_first_pass
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 fail. 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.
MODULE TYPES PROVIDED
The auth and account module types are provided.
RETURN VALUES
PAM_AUTH_ERR
Authentication failure.
PAM_AUTHTOK_RECOVERY_ERR
Authentication information cannot be recovered.
PAM_BUF_ERR
Memory buffer error.
PAM_CONV_ERR
Conversation failure.
PAM_SERVICE_ERR
Error in service module.
PAM_SUCCESS
Success.
PAM_USER_UNKNOWN
User not known to the underlying authentication module.
EXAMPLES
auth sufficient pam_userdb.so icase db=/etc/dbtest.db
