pam_selinux(sshd:session): Error! Unable to set executable context

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 

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

 

pam_selinux(sshd:session): Error!  Unable to set executable context €‡\     ialuser_u:sysadm_r:sysadm_t.

pam_selinux(sshd:session): Error!  Unable to set executable context €×ª_ialuser_u:sysadm_r:sysadm_t:s0.

pam_selinux(sshd:session): Error!  Unable to set executable context €gb     ialuser_u:sysadm_r:sysadm_t.

pam_selinux(sshd:session): Error!  Unable to set executable context € ³_ialuser_u:sysadm_r:sysadm_t:s0.

 

 

/etc/pam.d/sshd looks as follows

 

#%PAM-1.0

auth       required     pam_stack.so service=system-auth

account    required     pam_nologin.so

account    required     pam_stack.so service=system-auth

password   required     pam_stack.so service=system-auth

session    required     pam_stack.so service=system-auth

session    required     pam_loginuid.so

session    optional     pam_keyinit.so force revoke

session    required     pam_selinux.so

 

 

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