Getting Kodi to connect to DSM 7 Synology WebDAV service

I have been trying for the last little while to connect to my Synology WEBDav service for the past little while http not https version and it seems that I am hitting the right address but the way Kodi is trying to connect to the Synology WebDev service is causing it to fail authentication, my server sees it trying to connect but fails to authenticated I tested the user account and everything using RaiDrive and can get it to connect just not Kodi. Any suggestions ?

Ya I try to connect using the http version with the correct port Synology by default is 5005, I know I have the right setup as I can see in the log from Synology that the kodi box is hitting the server I just get an error saying the client failed to authenticate (wrong username/PW), when i look at the string kodi is using it not just dav://user:pas@IP:Port/ it adds some extra stuff in the password field like %26 ect.. I tried to clean it up but still no luck. i know the user name and password I type in the gui is correct as I tested it from my windows machine above and got it to connect. The error in Synology is: User [insert user] from [Kodi Ip] failed to log in via [WebDAV] due to authorization failure, not sure if Kodi has some problems translating the dav protocol or something I am using a nightly build from remembered 17th?
