1Please see the README for instructions common to all platforms and 2descriptions of the options mentioned here. 3 4 5 Linux. 6 7Most modern Linux distributions use Linux-PAM with a password changing 8module which understands "use_authtok". Thus, you may choose which 9module prompts for the old password, things should work either way. 10 11 12 FreeBSD. 13 14Currently, FreeBSD doesn't use PAM for password changing. This means 15you won't be able to use pam_passwdqc with FreeBSD. 16 17 18 Solaris. 19 20pam_passwdqc has to ask for the old password during the update phase. 21Use "ask_oldauthtok=update check_oldauthtok" with pam_passwdqc and 22"use_first_pass" with pam_unix. 23 24You will likely also need to set "max=8" in order to actually enforce 25not-so-weak passwords with the obsolete "traditional" crypt(3) hashes 26that most Solaris systems use. Of course this way you only get about 27one third of the functionality of pam_passwdqc. 28
