Description of problem: I use pam_mysql for a service that queries pam_mysql first, then tries to authenticate against the regular pam_unix module. My pam configuration is thus: /etc/pam.d/foo: auth sufficient pam_mysql.so XXXXX try_first_pass=false use_first_pass=false auth required pam_unix.so XXXXX try_first_pass=false use_first_pass=true The idea is that the password should only be asked once, by the pam_mysql module and should be passed down to the other modules. Now if the database specified in pam_mysql is down, the password is never asked and authentication against pam_unix always fails (even for a valid UNIX account). Version-Release number of selected component (if applicable): pam_mysql-0.7-0.4.rc1.fc8.i386 pam-0.99.8.1-17.1.fc8.i386 How reproducible: Always. Steps to Reproduce: 1. Create a /etc/pam.d/foo with the following lines: auth sufficient pam_mysql.so host=/path/to/file/that/does/not/exists try_first_pass=false use_first_pass=false auth required pam_unix.so use_first_pass Note that I am intentionally asking pam_mysql to point to a DB that is not there. 2. Try to login against the 'foo' pam service. Actual results: Password is never asked. Expected results: Password should be asked, and pam_unix should do its job even if pam_mysql cannot.
Created attachment 319180 [details] Patch fixing the problem. The attached patch fixes the problem. The PAM_AUTHTOK item is always set, even if pam_mysql fails to connect to its DB. Additionally, when use_first_pass or try_first_pass are true, and there is no password provided, then the DB is not even queried because the password check is always going to fail. Phil.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
