Re: ldap load measuring and reproduction tools

Well at the risk of getting seriously off-topic here (and/or turning this
into a flame-war) - this is not necessarily so. Some LDAP products let you
do replication based on search filters - which (for replication purposes)
effectively give you the same flexibility benefits as the hierarchical
structure, but without the high-maintenance downside inherent to the
hierarchical structure. If the business needs change, you can simply change
the filters to meet them and you're all done. Also, some LDAP server
products let you do something you might consider calling 'cascaded
replication' - where ldap server A replicates to server B, and server B
replicates to server C. This then takes the replication induced load of the
single master server you have. And lastly, some products let you set up
multiple master servers, increasing the availability and scalability of the
'write' part of LDAP as well. It's just that the product currently used
can't/doesn't. So the position im currently in can just as easily be viewed
as a shortcoming of the product currently used, as opposed to a fundamental
flaw in the layout of the directory.
The scalability problems which you will inevitably encounter will be a
direct result of this poor design.
As a result of this poor design which you have to work with, you are now
placed in the position in which everything else you do is going to be far
Sorry, not my style.
My advice: Try to get assigned to a different project. Save yourself while
you still can!
Im currently considering to advise migrating to a product that does support
all of the features mentioned above, and wait with adding all of the
proposed replica's until such a migration is completed.
Thanks for providing the feedback though,
