Tree - Users - 500 Internal Server Error

[utianayuba]

Hi,

Try to use this with number of users is around 1500.
The error appear when I click the Users tree.
The error message on the web:
"The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application."

::ffff:172.17.1.1 - - [04/Jun/2016 02:10:41] "GET /tree/CN=Users,DC=example,DC=com HTTP/1.1" 500 -
Any suggestion on this?

Best,

Can you see if something like this fixes it? http://paste.ubuntu.com/16960089/

[stgraber]

I'm not finding much information on the exact type of that field...

It's clearly not a string since that's what caused the error, it doesn't appear to be a list either, so kinda hoping it can be unpacked as a uint.

Hi,

That patch resulting different error messages:

Best,

Fun, so not something that can be represented as a uint...
