/etc/pam.d/system-auth contains the following line: -session optional pam_cap.so This is causing errors like: sudo[182047]: PAM unable to resolve symbol: pam_sm_open_session sudo[182047]: PAM unable to resolve symbol: pam_sm_close_session sshd[1054262]: PAM unable to resolve symbol: pam_sm_open_session sshd[1054262]: PAM unable to resolve symbol: pam_sm_close_session This is due to pam_cap module provides only auth type, so it's typical usage is: auth required pam_cap.so
