Hi all,
Thank you all for your help. I've gotten DNA working. I'll be doing some further work to convince myself that I understand exactly what I did that got it working and can replicate it; but in the meantime, I had a question or two.
Do I correctly understand RHDS 11 Administration Guide, section 7.4.3.1, to mean that if I want to have DNA manage uidNumber and gidNumber separately using different ranges, I'll need to create two instances of the plugin?
I'm not finding dsconf on CentOS 7, including under "yum whatprovides '*/dsconf'". Am I missing something? Was this tool released in something more recent than 1.3.7.5-28?
I suspect that the key differences between my original setup and what's working now are the establishment of a dnaSharedCfgDN and non-overlapping initial ranges. My original test setup was a single master server, which didn't need these things. It was suggested that I may need to include the attribute I wanted DNA to manage as part of creating an entry, and that I should give it dnaMagicRegen's value. However, this does not appear that it's necessary - I was able to add a test user without specifying a uidNumber and DNA generated it for me.
Thanks,
James

I've been trying a few things and have a different error message now but the same result. I'll update the thread shortly with further details.
