Hi All,

Thanks for the information.

But after resetting the semanage User/login, and moving the targeted folder
to old one and then install the default target. then also its still showing
the
Id context as context=*system_u:system_r:unconfined_t:s0-s0:c0.c1023.*

*What I observed is after changing the permission using semanage command
also, its still showing the system_u:system_r. *

*Check the semanage login/User output :*

*semanage login -l*

*Login Name           SELinux User         MLS/MCS Range        Service*

*__default__          unconfined_u         s0-s0:c0.c1023       **
*root                 unconfined_u         s0-s0:c0.c1023       **
*system_u             system_u             s0-s0:c0.c1023       **


*semanage user -l*

*                Labeling   MLS/       MLS/                          *
*SELinux User    Prefix     MCS Level  MCS Range
SELinux Roles*

*guest_u         user       s0         s0
 guest_r*
*root            user       s0         s0-s0:c0.c1023
 staff_r sysadm_r system_r unconfined_r*
*staff_u         user       s0         s0-s0:c0.c1023
 staff_r sysadm_r system_r unconfined_r*
*sysadm_u        user       s0         s0-s0:c0.c1023
 sysadm_r*
*system_u        user       s0         s0-s0:c0.c1023
 system_r unconfined_r*
*unconfined_u    user       s0         s0-s0:c0.c1023
 system_r unconfined_r*
*user_u          user       s0         s0
 user_r*
*xguest_u        user       s0         s0
 xguest_r*


Looks like its related to some other issue. What you think about this.

Thanks
Aman
