Configure Linux to authenticate users

To enable local user authentication, you first configure Linux so that IXIA TEXTML Server can use the same authentication credentials as Linux.

Linux OS uses pluggable authentication modules (PAM) for authentication.

To configure Linux to authenticate users:

Open a command line interface (CLI) to the Linux server running TEXTML Server.
Go to the pam.d directory:
```
cd /etc/pam.d
```
Create a symbolic link (symlink) to the textmlserver folder:
```
ln -s system-auth textmlserver
```
The system responds:
```
ln: creating symbolic link 'textmlserver' to 'system-auth'
```
Any user who belongs to a group that has PAM access can now sign in to the TEXTML Server.

Note: The TEXTML Server's user identity must also be able to run this authentication stack.

Note: Alternatively to the above procedure, you can copy the system-auth file located in the /etc/pam.d directory to the textmlserver file.
