Re: LDAP server connection question

[<CZa...@wi...>]

Do have an example of this?  The application that I have is in Perl/CGI.
It searches the LDAP server for employee info and then displays the
returned data in a table format in HTML.  The could be instances where the
main server is unavailable and the end users will not be happy to see
connection error messages in their web browsers.

Thanks

Some of the gurus (Graham, Chris, etc.) may have a slicker way of doing
this,
than what I do, but my method works well for me in doing web pages where
I desire fast responses (if possible).

What I do is:

  use an array of hosts to do the 'init' against, keeping my returned
objects
  in a hash.  Hosts that can't answer the init get skipped... i.e. they
don't
  get put into the hash.

  the bind operation works on the hash, and unsuccessful binds, get removed
  from the hash and the old ldap object get removed.

  queries are then put against 1 or more of the ldap objects in the hash,
   depending on what I want to do.  When checking for DSA busy, I usually
have
   a piece of 'delay/retry' code that gets around this, as DSA busy is not
   considered fatal until you continue to fail consistently.
   (well I don't consider it fatal :)


  I've found that doing it this way, gives me greater options and
flexibility.
  example, I could use it to make modifications of the same object on two
  different LDAP servers.  Although this is not my current use for it.

  My methodology also includes some fore thought on the servers in my
array...
  I use the closest(physically) server and work my way back to the
'master'.


Again, this may not work for you, but it's worked well enough for me that I
wrote a module to handle the work and include it into all my web code.
