Certificate

Hello,
	I installed a self signed certificate in SQL Server 2005, using
http://blogs.msdn.com/b/sql_protocols/archive/2007/06/27/install-a-self-sign
ed-test-certificate-that-can-be-loaded-by-sql-server-automatically.aspx.  I
then used tsql to connect to this server without any problems.  

Question 1:  Should I have done anything else?  It just surprised me that I
did not have to do anything else.  I am sure it is ignorance on my part, but
just making sure.

Question 2:  Is there any way to reference a certification file?  I don't
know if I need to yet, but might as well ask now just in case.


Here is my configuration file ( from freetds.conf ).
	[MyServer2005]
	    host = 192.168.254.91
	    port = 1433
	    tds version = 8.0
	    encryption = required

Here is my tsql version:
	[tonyb:v9_odbc:V3_18]> tsql -C
	Compile-time settings (established with the "configure" script)
	                            Version: freetds v0.91.dev.20110409RC1
	             freetds.conf directory: /usr/local/etc
	     MS db-lib source compatibility: no
	        Sybase binary compatibility: no
	                      Thread safety: yes
	                      iconv library: yes
	                        TDS version: 5.0
	                              iODBC: no
	                           unixodbc: yes
	              SSPI "trusted" logins: no
	                           Kerberos: no
	[tonyb:v9_odbc:V3_18]>


Thanks for your help.
