I'm a bit surprised, because my test was on 10.4. I'd've expected a more 
recent version under 10.5. We got an XServe with Leopard Server today, so 
here's what I get there:

$ strings /usr/lib/libsasl2.dylib | grep 2\.1
2.1.22

Especially since 10.4 *is* 2.1.18.

Maybe there's a realm in there? I only vaguely remember how that part works 
... I think there are people on this list who are more qualified than me to 
answer that.
