perfSONAR User Q&A and Other Discussion

[<>]

Hello,

I installed the perfSONAR 4.0.2 toolkit on the server with CentOS 7. After
completing the settings following the documentation, the web page showed a
internal server error. So we found this error in Esmond Django logs, 'password
authentication failed for user "esmond" '. 

I did not set up any passwords for Esmond and I have tried on re-installing
esmond and rebooting the server but nothing worked. I'd appreciate if anyone
could point out any missed steps or problems.
