Since 1.1.1-alt2, pam_sm_open_session() attempts to inherit /tmp/.private directory permissions from /home directory. However, the corresponding chmod(2) call may fail, e.g. due to EXT2_APPEND_FL flag set on /tmp/.private directory. In that case, pam_sm_open_session() should fail iff /tmp/.private directory permissions are less strict than requested.
pam_mktemp-1.1.1-alt3 -> sisyphus: * Mon Sep 05 2011 Dmitry V. Levin <ldv@altlinux> 1.1.1-alt3 - Fixed regression introduced in the previous release (closes: #26235).
