Thank you for your suggestions.

The real problem is Rational Technical support.  When you pay someone 100k+ 
they tend to look for any excuse to deem you "unsupported".  If you don't have 
your default group set to the clearcase user group, then technical support 
will decide that thats where your problem is!  I am sure you know how that 

I have solved problems like this in the past with the group sticky bit.  I 
agree this is the "correct" way to do this.  The only trouble with ClearCase 
is they use a kernel patch to enable some kind of custom modified file system. 
 I suspect it just will not work without the default group set :(

Go figure, we get the best and most responsive help from the part we paid 
nothing for.
