Hi,

I have Condor running in our Desktops that authenticate through 
OpenLDAP. Version is 6.7.5, but I was earlier running 6.6.7 without the 
issue you are talking about. The point to note is that all our desktops 
are x86. There is a dual Opteron desktop but that is not in the Condor 
pool. I could try to test that box if you are interested.
