Invalid security context messages

[Anamitra Dutta Majumdar]

We have removed the unconfined domain from our system based on RHEL6.
After that when we run audit2allow we see the following messages

[root@vos-cm148 ~]# audit2allow -a
libsepol.context_from_record: invalid security context:
"sysadm_u:system_r:useradd_t:s0-s0:c0.c1023"
libsepol.context_from_record: could not create context structure
libsepol.context_from_string: could not create context structure
libsepol.sepol_context_to_sid: could not convert
sysadm_u:system_r:useradd_t:s0-s0:c0.c1023 to sid

Are these harmful? What do they mean and how can we get rid of them.

Thanks,
Anamitra
