Another solution is to obtain and install a wildcard certificate (which 
will be good for all *.tib.com). 

That's the good news.  The bad news is that the commercial certificate 
authorities charge extra for wildcard certificates because they know 
they're more valuable to you (and not because it costs them anything 
extra in creating them, except maybe lost sales of certificates for 
specific names). 

BTW, you can get free certificates from http://cacert.org (no 
affiliation except as a user), though the first time your users see them 
they may have to answer a pop-up about a "funny" certificate.  (My 
experience is that most users just click OK and don't give it much 
thought.  The ones who do think about it tend to be more sophisticated 
anyhow, so they can sort it out rather than just switching off the 
computer in a panic and watching TV for the rest of their lives.)
