The Linux-PAM return values

Variants

System_Err = 4

System error

Success = 0

Successful function return

Open_Err = 1

dlopen() failure when dynamically loading a service module

Symbol_Err = 2

Symbol not found

Service_Err = 3

Error in service module

Buf_Err = 5

Memory buffer error

Perm_Denied = 6

Permission denied

Auth_Err = 7

Authentication failure

Cred_Insufficient = 8

Can not access authentication data due to insufficient credentials

Authinfo_Unavail = 9

Underlying authentication service can not retrieve authentication information

User_Unknown = 10

User not known to the underlying authentication module

MaxTries = 11

An authentication service has maintained a retry count which has been reached. No further retries should be attempted

New_Authtok_Reqd = 12

New authentication token required. This is normally returned if the machine security policies require that the password should be changed beccause the password is NULL or it has aged

Acct_Expired = 13

User account has expired

Session_Err = 14

Can not make/remove an entry for the specified session

Cred_Unavail = 15

Underlying authentication service can not retrieve user credentials unavailable

Cred_Expired = 16

User credentials expired

Cred_Err = 17

Failure setting user credentials

No_Module_Data = 18

No module specific data is present

Conv_Err = 19

Conversation error

AuthTok_Err = 20

Authentication token manipulation error

AuthTok_Recovery_Err = 21

Authentication information cannot be recovered

AuthTok_Lock_Busy = 22

Authentication token lock busy

AuthTok_Disable_Aging = 23

Authentication token aging disabled

Try_Again = 24

Preliminary check by password service

Ignore = 25

Ignore underlying account module regardless of whether the control flag is required, optional, or sufficient

AuthTok_Expired = 27

Critical error (?module fail now request)

Abort = 26

user’s authentication token has expired

Module_Unknown = 28

module is not known

Bad_Item = 29

Bad item passed to pam_*_item()

Conv_Again = 30

conversation function is event driven and data is not available yet

Incomplete = 31

please call this function again to complete authentication stack. Before calling again as isize, verify that conversation is completed

Trait Implementations

impl Clone for PamReturnCode

fn clone(&self) -> PamReturnCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PamReturnCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PamReturnCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<PamReturnCode> for PamError

fn from(err: PamReturnCode) -> PamError

Converts to this type from the input type.

impl From<i32> for PamReturnCode

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for PamReturnCode

fn eq(&self, other: &PamReturnCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
