authentication error

[tloubrieu]

I am trying to connect with admin rights so to harvest some other server.

I have created a record in postgresql in table useraccount:
1;"admin";"admin";TRUE;TRUE

When I am trying to login on : http://localhost:8080/oss/login

The following url has an error (seen on debug in chrome) : http://localhost:8080/oss/j_spring_security_check

The tomcat log file contains the following exceptions:

Do you know where the problem is ?

Thanks,

Hi! No, no idea :-(. The login feature is in an alpha status and was developed by a student during Google Summer of Code. It is only relevant for the feature to harvest external data sources using scripting language and the "sensor provider" approach (https://wiki.52north.org/bin/view/Projects/GSoC2013OpenSensorSearch#Alternative_harvesting_Techinque), which were planned to be uploaded using a web form. This feature is also in alpha stage, sorry! I would have to check the code in detail, which I cannot do in the next days.

What kind of server do you want to harvest? An SOS, maybe? Because that should work using the Harvest operation of the SIR interface, even without logging in.

That's find with me. I just tried to log in because I expected this to be mandatory to harvest.
I am going to test the free SOS harvesting function.

I am not closing the issues as it is still there although not critical for me at the moment.
