Hi
The minding to deploy dot1x smoothly with less impact is following a 3 step deployment: Monitor, low impact and close mode.
This allows you to create rules and validate that users are authenticated well. If, for some reasons, users aren't able to authenticate they won't be impacted in monitor mode and few impacted in low impact mode. When everything is configured will then you can move forward with close mode.
I can share some configuration but it won't help if you don't get how it works.
I would suggest to read the 2 links below and you should be able to begin your config. Then if you have issues I can help.
