Emmanuel helped me a lot when I added the new section to the wiki more
than 2 years ago. The users mailing list thread carried the subject
"ApacheDS 2.0.0-M23 non-gui adding a partition".
I am slowly working my way through migration of my ubuntu 16.04 LTS i386
apacheds M23 production system to an ubuntu 18.04 LTS amd64 AM25
platform. I won't bore you with my war stories, but I intend to reflect
some of my lessons learnt in the wiki.
I've had a painful and frustrating time trying to follow my own
instructions in the wiki! Eventually, I realised my M23 partition was
working fine /even though/ its ads-contextentry value has always been
completely wrong! I haven't investigated how this might have happened,
but I want to be sure the new partition I create on my AM25 system is
correct.
I have created a series of scripts and crib sheets to document clearly
how the ads-contextentry base64 hash has been generated for the example
partition. However, I now realise I am not 100% clear how to create a
valid base64 for my own partition.
By carefully hashing 4 specific lines of the example root entry I can
generate the correct hash. These lines are:
dn: dc=example,dc=com
dc: example
objectclass: domain
objectclass: top
The dn value corresponds to the ads-partitionsuffix attribute. The dc
value corresponds to the ads-partitionid attribute.
The objectclass value of top is required in all ldapobjects, but I don't
see where the "objectclass: domain" comes from, or even why it is
specified before top, because their respective orders will alter the
value of the base64 hash.
Also, I am puzzled about what ldapattributes I need to hash for my own
partition. It's top-level ldapentry follows the "old school" convention,
and I am very reluctant to change it because there are so many
dependencies within the directory, but also the various applications
which rely on the directory.
The top entry looks like this:
dn: O=PingToo.com
objectclass: top
objectclass: organization
o: PingToo.com
Obviously, the order of these attributes and also the exact use of
letter case (and any white space ) will alter the resultant
ads-contextentry hash.
Can anyone offer me some advice on how and why to do this correctly, please?
Once I have successfully created my new partition I hope to understand
the algorithm properly and will update the wiki page to explain the
process more clearly.
Regards,
Brian
