====== Ubuntu - PAM - Check is a program can use PAM ======

To employ PAM, an application needs to be “PAM aware“.

It needs to have been written and compiled specifically to use PAM.

To find out if a program is “PAM-aware” or not, check if it has been compiled with the PAM library using the **ldd** command

----

===== Example =====

Check if Samba can use PAM.

<code bash>
sudo ldd /usr/sbin/samba | grep libpam.so
</code>

returns:

<code bash>
	libpam.so.0 => /lib/x86_64-linux-gnu/libpam.so.0 (0x00007f5eb06fd000)
</code>

This shows that PAM can be used.
