Hi all, Running as an ordinary user, straight from the beginning. Is the (default) suid of/usr/bin/su causing this? Anyway: the info requested: /var/log/secure will tell: Nov 24 11:04:11 fedora23-server su: pam_systemd(su:session): Cannot create session: Already running in a session Nov 24 11:04:11 fedora23-server su: pam_unix(su:session): session opened for user root by testuser(uid=10005) De pam.d files are from a clean fresh Fedora23 install and ipa-client-install afterwards: /etc/pam.d/su #%PAM-1.0 auth sufficient pam_rootok.so # Uncomment the following line to implicitly trust users in the "wheel" group. #auth sufficient pam_wheel.so trust use_uid # Uncomment the following line to require a user to be in the "wheel" group. #auth required pam_wheel.so use_uid auth substack system-auth auth include postlogin account sufficient pam_succeed_if.so uid = 0 use_uid quiet account include system-auth password include system-auth session include system-auth session include postlogin session optional pam_xauth.so /etc/pam.d/postlogin #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. session [success=1 default=ignore] pam_succeed_if.so service !~ gdm* service !~ su* quiet session [default=1] pam_lastlog.so nowtmp silent session optional pam_lastlog.so silent noupdate showfailed /etc/pam.d/system-auth #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required pam_env.so auth [default=1 success=ok] pam_localuser.so auth [success=done ignore=ignore default=die] pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 1000 quiet_success auth sufficient pam_sss.so forward_pass auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 1000 quiet account [default=bad success=ok user_unknown=ignore] pam_sss.so account required pam_permit.so password requisite pam_pwquality.so try_first_pass local_users_only retry=3 authtok_type= password sufficient pam_unix.so sha512 shadow nullok try_first_pass use_authtok password sufficient pam_sss.so use_authtok password required pam_deny.so session optional pam_keyinit.so revoke session required pam_limits.so -session optional pam_systemd.so session optional pam_oddjob_mkhomedir.so umask=0077 session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so session optional pam_sss.so Op 24-11-15 om 10:37 schreef Jakub
Hrozek:
re you running su as an ordinary user or root? What does appear in /var/log/secure when you run su ?Can you show what is the /etc/pam.d/su config and the config of the service that is included from /etc/pam.d/su ? (typically system-auth) |
