What is wrong with file permission?
Friends,

I have weird problem with my Linux OS.

I have few files which is owned by root but could not be modified (edit, chmod, chown etc)

Code:
[root@ip-10-34-70-117 ~]# id
uid=0(root) gid=0(root) groups=0(root)
[root@ip-10-34-70-117 ~]# whoami
root
[root@ip-10-34-70-117 ~]# ls -l /etc/security/access-sshd.conf
-rw-r--r-- 1 root root 431 Jun 22 03:31 /etc/security/access-sshd.conf
[root@ip-10-34-70-117 ~]# mv /etc/security/access-sshd.conf /etc/security/access-sshd.conf1
mv: cannot move ‘/etc/security/access-sshd.conf’ to ‘/etc/security/access-sshd.conf1’: Permission denied
[root@ip-10-34-70-117 ~]# chmod 777 /etc/security/access-sshd.conf
chmod: changing permissions of ‘/etc/security/access-sshd.conf’: Permission denied
[root@ip-10-34-70-117 ~]# rm -rf /etc/security/access-sshd.conf
rm: cannot remove ‘/etc/security/access-sshd.conf’: Permission denied
[root@ip-10-34-70-117 ~]#

Appreciate your input in this regard.

Thanks
Bala

ssh-ldap-helper

SSH-LDAP-HELPER(8)					    BSD System Manager's Manual 					SSH-LDAP-HELPER(8)

NAME

     ssh-ldap-helper -- sshd helper program for ldap support

SYNOPSIS

     ssh-ldap-helper [-devw] [-f file] [-s user]

DESCRIPTION

     ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP.  ssh-ldap-helper is disabled by default and can only be enabled in the
     sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''.

     ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper.

     The options are as follows:

     -d      Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog.

     -e      Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file.

     -f      ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default).

     -s      ssh-ldap-helper prints out the user's keys to stdout and exits.

     -v      Implies -d; increases verbosity.

     -w      ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file.

SEE ALSO

     sshd(8), sshd_config(5), ssh-ldap.conf(5),

HISTORY

     ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP .
