No problem. I've taken care of that.

I did read that and incorporated it in my plan, in a slightly modified form.

So this may be a more common problem.

That's correct. Normal users can log in but the DC could not.

I have now done that. I created "dcbsu" in addition to "bsudc"

The new "dcbsu" account was created with filesystem authentication and worked fine. I logged in to the web interface using that account, and searched for my old domain coordinator "bsudc". I then changed its authentication from filesystem to internal and now both DCs work fine. :-)
Of course, this still does not answer the question of why the old DC did not work following the OS upgrade or how to avoid it. (A very important question for anyone who wants to do this in the future, including possibly me.)
The other obvious remaining question is whatever happened to rolesmanip.pl? The internal documentation in /root/loncapa-2.7.1/loncom/build/make_domain_coordinator.pl indicates that there should be a manual procedure for adding a domain coordinator. When I traced through that manual procedure, I got through the first 8 steps (finding that nothing needed to be done for them) and then tried in vain to find a file called rolesmanip.ip. Not only is it not anywhere under /root/loncapa-2.7.1, but I still have tarballs going all the way back to loncapa-1.3.2.tar.gz and none of them contain a file called rolesmanip.pl. So the question is whether the filename inside make_domain_coordinator.pl is incorrect and I should have been looking for a different filename or whether there is really no manual procedure at all.
Anyway, I've been trying to write up a report on the procedure I used to do the upgrade, including the pitfalls I have encountered. I'd like to include something about this part too. Once I decide that I know as much as I am going to know, I'll submit it to this list.
Best Regards to all,
