pam_canonicalize_user - Man Page

pam_canonicalize_user.so

This PAM module uses the name of the user obtained via pam_get_user(3) as a key to query the password database, and replaces PAM_USER with the pw_name value that has been returned.

This module does not recognise any options.

Only the auth module type is provided.

PAM_IGNORE

The user name was set successfully.

PAM_USER_UNKNOWN

The user was not found.

PAM_SYSTEM_ERR

The application did not supply neither a user name nor a conversation method.

PAM_INCOMPLETE

The conversation method supplied by the application is waiting for an event.

PAM_CONV_ERR

The conversation method supplied by the application failed to obtain the user name.

PAM_ABORT

PAM_BUF_ERR

Memory buffer error.

Prepend the PAM auth stack with the following line to canonicalize the user name before the authentication:

        auth required pam_canonicalize_user.so

pam_get_user(3), pam_get_item(3), pam_set_item(3), getpwnam(3), pam.conf(5), pam.d(5), pam(8)
