Yes, I had that problem when we switched from Sys V 3.0 to 3.1 a while
back. A PC file server application by Locus (PC-Interface version 2.8.7)
broke. Basically, it allows DOS users access to the UNIX file system as 
a DOS drive and does its own user validation during its login. Obviously,
when user phredd entered his password, PC-Interface was looking for the
password in passwd and not shadow. The result was that there were a lot
of angry dos users at me. (eh, so what... :-)

Anyway, the warning is a valid one if you have any software that does
its own user validation with passwords. I just wish the warning you 
mentioned was in *MY* manual as well!
 
The fix was to get version 2.8.7.1 :-)   (No, for real, weird version #s!!)
