This is not something you should do by a cook book approach.  You should 
understand what you are doing.  The security of your communications is 
at risk.

In particular, you should not tell people to accept an invalid 
certificate unless you understand the precise nature of the problem, and 
you have done a risk analysis.  If that risk analysis indicates that the 
risk to the users of your system is acceptable, you should still tell 
people that they should never accept an invalid certificate without 
management authority.  (A recently expired certificate is a very low 
risk, but one that doesn't match the server should ring alarm bells.)
