NAME
pam_unix_cred - PAM user credential authentication module for UNIX
SYNOPSIS
pam_unix_cred.so.1
DESCRIPTION
The pam_unix_cred module implements pam_sm_setcred(3PAM). It provides
functions that establish user credential information. It is a module
separate from the pam_unix_auth(7) module to allow replacement of the
authentication functionality independently from the credential func‐
tionality.
The pam_unix_cred module must always be stacked along with whatever
authentication module is used to ensure correct credential setting.
Authentication service modules must implement both pam_sm_authenti‐
cate() and pam_sm_setcred().
pam_sm_authenticate() in this module always returns PAM_IGNORE.
pam_sm_setcred() initializes the user's project, privilege sets, ini‐
tializes or updates the user's audit context if it hasn't already been
initialized, and sets the process clearance.
The new clearance is set to the lower bound of the current process
clearance and the minimum label returned by getuserrange(3TSOL). If
these two labels are disjoint, the clearance is set to the greatest
lower bound.
The following flags may be set in the flags field:
PAM_ESTABLISH_CRED
PAM_REFRESH_CRED
PAM_REINITIALIZE_CRED
Initializes the user's project to the project specified in
PAM_RESOURCE, or if PAM_RESOURCE is not specified, to the user's
default project. Establishes the user's privilege sets.
If the audit context is not already initialized and auditing is
configured, these flags cause the context to be initialized to that
of the user specified in PAM_AUSER (if any) merged with the user
specified in PAM_USER and host specified in PAM_RHOST. If PAM_RHOST
is not specified, PAM_TTY specifies the local terminal name.
Attributing audit to PAM_AUSER and merging PAM_USER is required for
correctly attributing auditing when the system entry is performed
by another user that can be identified as trustworthy.
If the audit context is already initialized, the PAM_REINITIAL‐
IZE_CRED flag merges the current audit context with that of the
user specified in PAM_USER. PAM_REINITIALIZE_CRED is useful when a
user is assuming a new identity, as with su(8).
PAM_ESTABLISH_CRED
PAM_REINITIALIZE_CRED
Prompt for an "audit record annotation string" for a PAM_USER, who
is configured to request audit record annotation.
PAM_DELETE_CRED
This flag has no effect and always returns PAM_SUCCESS.
The following options are interpreted:
debug Provides syslog(3C) debugging information at the
LOG_DEBUG level.
nowarn Disables any warning messages.
noannotation Do not prompt for audit record annotation. It is
an error to include this option and the annota‐
tion_prompt= option.
annotation_prompt= Provides a prompt string to override the default
audit record annotation prompt of Session Annota‐
tion:. The prompt string must immediately follow
the =. If the string following the = contains
white space, it must be surrounded by quotation
marks, for example annotation_prompt=My Prompt
String. It is an error to include this option and
the noannotation option.
ERRORS
Upon successful completion of pam_sm_setcred(), PAM_SUCCESS is
returned. The following error codes are returned upon error:
PAM_CRED_UNAVAIL Underlying authentication service cannot retrieve
user credentials
PAM_CRED_EXPIRED User credentials have expired
PAM_USER_UNKNOWN User is unknown to the authentication service
PAM_CRED_ERR Failure in setting user credentials
PAM_BUF_ERR Memory buffer error
PAM_SERVICE_ERR An illegal option
PAM_SYSTEM_ERR System error
The following values are returned from pam_sm_authenticate():
PAM_IGNORE Ignores this module regardless of the control flag

NOTES
The interfaces in libpam(3LIB) are MT-Safe only if each thread within
the multi-threaded application uses its own PAM handle.
If this module is replaced, the audit context and credential may not be
correctly configured.
