* When root tries to su to a non-existent user, pam_authenticate() willDag-Erling Smørgrav2004-01-061-4/+4
| | | | | | | | | | | | normally succeed (because root can su to anyone), but pam_acct_mgmt() will most likely fail, causing su to log a confusing "pam_acct_mgmt: error in service module" message. To avoid this, call getpwnam() before pam_acct_mgmt(). Sponsored by: registrar.no Notes: svn path=/head/; revision=124166
* Be sure to restore foreground group to parent su before parent suDavid Xu2003-11-041-1/+2
| | | | | | | | exits, otherwise shell will be confused and does not set foreground group correctly for next su command. This sounds like a bug in sh. Notes: svn path=/head/; revision=122061
* It seems when su executes in a shell scripts, there is a timing race,David Xu2003-11-031-0/+2
| | | | | | | | | | | sometimes, su will receive a SIGTTOU when parent su tries to set child su's process group as foreground group, and su will be stopped unexpectly, ignoring SIGTTOU fixes the problem. Noticed by: fjoe Notes: svn path=/head/; revision=122013

* PAM-related improvements:Dag-Erling Smørgrav2003-04-081-37/+59
| | | | | | | | | | | - if operating "as them" (su -l), use pam_{open,close}_session() - allow PAM to override $HOME (pam_chroot needs this) - chdir early, because later on we may be chrooted and chdir will fail Also use pid_t instead of int where applicable. Notes: svn path=/head/; revision=113262

| | | | | | | | | | | signal never affects su directly, some shells changes its pgrp at running or suspended time, so a broadcast SIGTSTP from child will mess up su's job control. Discussed with: bde Notes: svn path=/head/; revision=112695
