NAME
pam_roles - Solaris Roles account management module SYNOPSIS
pam_roles.so.1 DESCRIPTION
The pam_roles module implements pam_sm_acct_mgmt(3PAM). It provides functionality to verify that a user is authorized to assume a role. It also prevents direct logins to a role. The user_attr(4) database is used to determine which users can assume which roles. The PAM items PAM_USER and PAM_AUSER, and PAM_RHOST are used to determine the outcome of this module. PAM_USER represents the new identity being verified. PAM_AUSER, if set, represents the user asserting a new identity. If PAM_AUSER is not set, the real user ID of the calling service implies that the user is asserting a new identity. Notice that root can never have roles. This module is generally stacked above the pam_unix_account(5) module. The following options are interpreted: allow_remote Allows a remote service to specify the user to enter as a role. debug Provides syslog(3C) debugging information at the LOG_DEBUG level. ERRORS
The following values are returned: PAM_IGNORE If the type of the new user identity (PAM_USER) is "normal". Or, if the type of the new user identity is "role" and the user asserting the new identity (PAM_AUSER) has the new identity name in its list of roles. PAM_USER_UNKNOWN No account is present for user. PAM_PERM_DENIED If the type of the new user identity (PAM_USER) is "role" and the user asserting the new identity (PAM_AUSER) does not have the new identity name in its list of roles. EXAMPLES
Example 1 Using the pam_roles.so.1 Module The following are sample entries from pam.conf(4). These entries demonstrate the use of the pam_roles.so.1 module: cron account required pam_unix_account.so.1 # other account requisite pam_roles.so.1 other account required pam_unix_account.so.1 # The cron service does not invoke pam_roles.so.1. Delayed jobs are independent of role assumption. All other services verify that roles can- not directly login. The "su" service (covered by the "other" service entry) verifies that if the new user is a role, the calling user is authorized for that role. Example 2 Allowing Remote Roles Remote roles should only be allowed from remote services that can be trusted to provide an accurate PAM_AUSERname. This trust is a function of the protocol (such as sshd-hostbased). The following is a sample entry for a pam.conf(4) file. It demonstrates the use of pam_roles configuration for remote roles for the sshd- hostbased service. sshd-hostbased account requisite pam_roles.so.1 allow_remote sshd-hostbased account required pam_unix_account ATTRIBUTES

The interfaces in libpam(3LIB) are MT-Safe only if each thread within the multi-threaded application uses its own PAM handle. This module should never be stacked alone. It never returns PAM_SUCCESS, as it never makes a positive decision. The allow_remote option should only be specified for services that are trusted to correctly identify the remote user (that is, sshd-host- based). PAM_AUSER has replaced PAM_RUSER whose definition is limited to the rlogin/rsh untrusted remote user name. See pam_set_item(3PAM). SunOS 5.11 6 Mar 2007 pam_roles(5)
