Authentication with PAM

Hello all,

I recently updated PAM policy files (pam_authz.policy) on HP-UX Servers with AD groups involving allowing and denying the certain groups..

Could anyone tell me what is the equivalent mechanism in SLES(Linux)? Is it possible to allow/deny AD group access with the SLES LDAP integration?

PAM.CONF(5)						      BSD File Formats Manual						       PAM.CONF(5)

NAME
pam.conf -- PAM policy file format DESCRIPTION
The PAM library searches for policies in the following files, in decreasing order of preference: 1. /etc/pam.d/service-name 2. /etc/pam.conf 3. /usr/local/etc/pam.d/service-name 4. /usr/local/etc/pam.conf If none of these locations contains a policy for the given service, the default policy is used instead, if it exists. Entries in per-service policy files must be of one of the two forms below: function-class control-flag module-path [arguments ...] function-class include other-service-name Entries in pam.conf-style policy files are of the same form, but are prefixed by an additional field specifying the name of the service they apply to. In both types of policy files, blank lines are ignored, as is anything to the right of a '#' sign. The function-class field specifies the class of functions the entry applies to, and is one of: auth Authentication functions (pam_authenticate(3), pam_setcred(3)) account Account management functions (pam_acct_mgmt(3)) session Session handling functions (pam_open_session(3), pam_close_session(3)) password Password management functions (pam_chauthtok(3)) The control-flag field determines how the result returned by the module affects the flow of control through (and the final result of) the rest of the chain, and is one of: required If this module succeeds, the result of the chain will be success unless a later module fails. If it fails, the rest of the chain still runs, but the final result will be failure regardless of the success of later modules. requisite If this module succeeds, the result of the chain will be success unless a later module fails. If it module fails, the chain is broken and the result is failure. sufficient If this module succeeds, the chain is broken and the result is success. If it fails, the rest of the chain still runs, but the final result will be failure unless a later module succeeds. binding If this module succeeds, the chain is broken and the result is success. If it fails, the rest of the chain still runs, but the final result will be failure regardless of the success of later modules. optional If this module succeeds, the result of the chain will be success unless a later module fails. If this module fails, the result of the chain will be failure unless a later module succeeds. There are two exceptions to the above: sufficient and binding modules are treated as optional by pam_setcred(3), and in the PAM_PRELIM_CHECK phase of pam_chauthtok(3). The module-path field specifies the name, or optionally the full path, of the module to call. The remaining fields are passed as arguments to the module if and when it is invoked. The include form of entry causes entries from a different chain (specified by other-system-name) to be included in the current one. This allows one to define system-wide policies which are then included into service-specific policies. The system-wide policy can then be modi- fied without having to also modify each and every service-specific policy. SEE ALSO
