An administrator would like to enable SELinux on a machine with the RSA Authentication Agent 7.1 for PAM. 

SELinux requires certain modules to be installed first, otherwise it will not work after installing the PAM agent.

The required modules for SELinux are not installed prior to installing the RSA Authentication Agent 7.1 for PAM.

Install the following modules on the machine prior to installing the Authentication Agent for PAM.

1. Install the RSA prerequisites:

• selinux-policy-devel.rpm
• noarchpolicycoreutils-devel.rpm

sudo yum install selinux-policy-devel*.noarch policycoreutils-devel*

2. Create the /opt/rsa directory.

mkdir /opt/rsa

3. Create a text file called   /opt/rsa/sdopts.rec    with the following content:

​CLIENT_IP=<IP address of the server on which you are installing the PAM agent>

4. Ensure that both the new sdopts.rec file and the sdconf.rec file are owned by root:root and have the permissions of 644 (owner can read/write, group and world read only):

chown root:root /opt/rsa/sdopts.rec
chmod 644 /opt/rsa/sdopts.rec
chownr root:root /opt/rsa/sdconf.rec
chmod 600 /opt/rsa/sdconf.rec

5. Make a backup copy of /etc/ssh/sshd_config file

cp /etc/ssh/sshd_config /etc/ssh/sshd_config.old

6. Update the /etc/ssh/sshd_config file to include the following values:

UsePam yes
PasswordAuthentication no
UsePrivilegeSeparation no
ChallengeResponseAuthentication yes
PublicKeyAuthentication no

7. Untar the PAM-Agent tar ball into any local directory.

tar -xvf <filename>.tar 

8. Execute the install_pam.sh shell script located in the PAM-Agent directory created from unpacking the tar ball.  Make sure to supply the correct path the sdconf.rec (/opt/rsa), otherwise you will use the default responses for all questions asked during the install.

/<filename>/install_pam.sh

9. Update the /etc/sd_pam.conf file such that the VAR_ACE variable points to the correct location of the sdconf.rec file located in /opt/rsa.
10. Update the /etc/pam.d/sshd file as follows:
    1. Comment out ALL lines containing "auth"
    2. Add the following line to the bottom of the file:

auth  required     pam_securid.so

11. Restart sshd.  As root, 

/usr/sbin/sshd restart

12. Test authentication by executing /opt/pam/bin/64bit/acetest.
13. Test SSH authentication from a remote host.

The following is the output from the install_pam.sh from the point that the EULA is accepted:

Do you accept the License Terms and Conditions stated above? (Accept/Decline) [D]A

Enter Directory where sdconf.rec is located [/var/ace]/opt/rsa

Please enter the root path for the RSA Authentication Agent for PAM directory [/opt]

The RSA Authentication Agent for PAM 7.1 will be installed in the /opt directory.
