We have an selinux user specialuser_u defined. The outputs of the semanage command are as seen below

semanager user –l

admin_u         user       s0         SystemLow-SystemHigh           system_r sysadm_r

guest_u         guest      s0         s0                             guest_r

remotesupport_u user       s0         SystemLow-SystemHigh           system_r sysadm_r

root            sysadm     s0         SystemLow-SystemHigh           system_r sysadm_r

specialuser_u   user       s0         s0                             system_r sysadm_r

staff_u         staff      s0         SystemLow-SystemHigh           sysadm_r staff_r

sysadm_u        sysadm     s0         SystemLow-SystemHigh           sysadm_r

system_u        user       s0         SystemLow-SystemHigh           system_r

Now, we see the following in our log files

/etc/pam.d/sshd looks as follows

Could anyone help us with why we are seeing these error messages and why the specialuser_u is corrupted with control chars?
