Mike, I've got no experience with LDAP, but when I read this my first suspicion instead is that this could just as well be an IIS limitation rather than an LDAP one. I would assume that since you refer to it being a web app, and using MS technologies, that you are using IIS for the web server.
If this is IIS 7, note that the "request filtering" feature (an option for IIS, which might have been turned on for security reasons) has a default limit of 30m (not 10). Still, it could be that someone lowered it. You can learn more, including how to view or change the value (which could be set at the site or server level within IIS, and either via XML changes or the UI) here: http://www.iis.net/configreference/system.webserver/security/requestfilterin g/requestlimits Do be aware that the value can be set at the server level (what that technote refers to as the "connection level"), or at the site level (which would override the server level setting), or even at an application or folder level (within a site) which would override the site level setting. You may want to at least check if the folder/app, site, or server level setting for your upload page might be set to 10mb. If so, you could raise it. If that's not it I'd still recommend you consider finding out if this is some other sort of IIS limit rather than LDAP. (But it could well be an LDAP limit, I suppose.) Let us know if that may help. /charlie -----Original Message----- From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Mike Staver Sent: Saturday, February 22, 2014 10:30 PM To: discussion@acfug.org Subject: [ACFUG Discuss] LDAP file size limit This isn't a specific ColdFusion question I realize, but I am not aware of a more knowledgeable group of programmers :) My question is this: does anyone know of a file size limit in LDAP? The server is running Windows 2008 R2, and an LDAP schema has been created and modified to contain user data for a web application I'm supporting. One of the things this application does is store user file uploads directly into LDAP. Up to this point, the files being uploaded have not been over 10 MB in size apparently. The users now have a need to upload files that are approximately 35 MB in size. What we are seeing is network disconnects from LDAP right at 10 MB. Meaning, if a user uploads a file of 9.99 MB in size, it works fine. Anything over that, it disconnects and kills the upload. I have researched as much as I can, but I have been unable to find many example of files being stored in LDAP from web applications. I realize there is probably a very good reason for this, but I can't change the current architecture of this application right now. The only LDAP server parameters I can find for windows are here: http://support.microsoft.com/kb/315071 http://msdn.microsoft.com/en-us/library/cc223376.aspx I can't find anything specific to the maximum size of an entry or row. Anybody out there who knows if there is a way to change LDAP so larger files can be stored via the web application? ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com ------------------------------------------------------------- ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com -------------------------------------------------------------
