Whenever I try to use User Service plugin, I get the following exception:

HTTP ERROR: 500

I have checked that the plugin is enabled, and I pass the secret pass correctly. I’m using Linux Mint, and libidn seems to be installed. Any idea about what may be causing this problem?

Regards


#2

I am having same problem. Any help on this?


#3

I’m also having this problem and I opened another thread about it.

Did any of you solved it?


#4

I’ve got this problem as well… I love the speedy support ignite are giving :frowning:


#5

I solved the problem by downloading the source for user service, downloading the gnu stringprep source code, and then compile both together to create a new binary.


#6

Thnx. I’ll try that.


#7

It works! thank you :slight_smile:


#8

is this the only solution ?


#9

Dear yadit,

Sorry for bad english.

Thanks,

Mayasakthi


#10

Hi on Debian (lenny) cant find librarys that compile,

Can you tell me the sources you were able to compile , THANKS


#11

I have just installed User Service plugin on Openfire 3.7.1 (from the Available plugins page). Then i have enabled commands processing for this plugin in its settings, copied the secret key and formed a special url to create a user. I was able to create a user this way without an exception.


#12

I’m sorry, I’m not that familiar with openfire - just installed this plugin and nothing more, so I can’t really help.


#13

Only solution I found…


#14

I just used google - I’m sorry, but I can’t find the link from where I got it…


#15

I have the same problem but i’m not familiar on building the plugin as suggested, can you provide me the binaries to replace the existing plugin? Please help me!!


#16

Just copy libidn.jar to /path/to/openfier/lib/ and restart openfire.
