your reputation for being *ahem* difficult precedes you, but i think it
should be amened to include being a hypocrite, too.  how does it feel?
you have been nothing but obtuse and dodgy yourself.

For instance it can be set through the users file in the authorize

well then, the authorize section has been moved out of the users file
and into the modules/ldap file, AND IS NOT DOCUMENTED FURTHER.
Moreover, my DN in LDAP is fully qualified:
uid=brendan,ou=Users,dc=bpk2,dc=com.  How you are determining the wrong
value and populating a variable with that wrong value is a broken
process.  if a variable named Ldap-UserDn is going to be used, then the
value of the DN in the tree is what i expect to find.  what about you?
i should not have to cobble together a value that claims to be collected

why not?  how are folks to know what they are?  given the berating they
get from the supposed help answering the mailing list, i doubt anyone
would every really get answers if they had to find out something in
particular.  oh, and the attributes...  the ones found here: THERE IS NOTHING ABOUT LDAP
ANYTHING.  disjointed documentation much?  in fact it seems that most
rlm_* attributes are not there at all.  so, whats the deal with that?
again, the users file references that, so why isnt it a complete

and thanks to the effort i have spent pulling your teeth, and rubbing
your ego, i now have some place to turn for research.  thanks.  this
could have been accomplished without you being a fuckchop 3 DAYS AGO.

well, if the info was not contradictory and was written to start at some
point, provided clear steps to perform and ended with an accomplished
goal, maybe 10 year old docs would not be better than the official wiki,
but alas...

isnt perfect?  the technical writing is utter rubbish.

i took 4 years of spanish in school, and learned nothing but vocabulary
and verb conjugation.  i cant speak the language to save my life, and
thats not for lack of effort.

i have read docs, comments, wiki pages, mailing lists, etc and have some
points that i know i can get to/through.  but, in no way, shape or form
can i call myself competent because no fundamental teachings exist on
where to start, what to do and how to get to a specific configuration
and successful implementation.  at best a hodge-podge of hacked together
directives are documented, isolated and atomically independent of any
larger effort to be undertaken.

i have been around the block.  i support several technologies for a
fortune 25 company.  our golden rule is the "grandma" test.  can the
docs i put together for a process/effort/change be given to my
grandmother and the work be done by her?  take a starting point, perform
deliberate steps (which include breakdowns of the commands with examples
or the actual command to be run), achieve the desired result, and
include a process to validate what is expected to be in place.

my grandma + your docs != work getting done.
