Unable to register database with DBCA

Attempting to register a database with DBCA and got the following error message:

TNS-04409: Directory service error caused by: oracle.net.config.DirectoryServiceException: TNS-04405: General error caused by: oracle.net.ldap.NNFLException

Thought thought perhaps the problem was something like this issue with password policys, but it turns out it was simply that I needed to change how anonymous binds are handled. Per Doc ID 947285.1, check the value of orclanonymousbindsflag. I had it set to "2", which didn't work. Setting it to "1" allowed me to register the database, and then I set it back to 2 as it is a more secure setting.
