The Solaris 8 HW 7/03 release introduced several new PAM modules:
pam_authtok_check(5)
pam_authtok_get(5)
pam_authtok_store(5)
pam_dhkeys(5)
pam_passwd_auth(5)
pam_unix_account(5)
pam_unix_auth(5)
pam_unix_session(5)
In the Solaris 8 HW 7/03 release, these modules replace the pam_unix(5) module. However, the Trusted Solaris 8 HW 7/03 release does not support these new modules. Instead, this release maintains documented use of the pam_unix(5) module as the required configuration.
