Uninstall OS X Server completely in Yosemite I recently run the OS X Server app on Yosemite. Now each time I shutdown or restart my mac, it asking for administrator password. I don't want to run my MacBook Pro as a server. I ran this app just to test something, now I want to reset to the previous state. Now I feel that there are some daemon process running because of the server app, that slows down my laptop.
How to uninstall or reset all the changes made by OS X Server app on Yosemite?
I got this solution by posting the same on apple discussion forum. I wanted to post the answer here because, it might help someone else. Many thanks to the friend who gave me this solution.

Move the Server application to the Trash. Delete the following items (some may not exist), then reboot:

/.ServerBackups
/var/db/.ServerSetupDone
/Library/Preferences/com.apple.serverd.plist
/Library/Preferences/com.apple.servermgr_accounts.plist
/Library/Preferences/com.apple.servermgr_certs.plist
/Library/Preferences/com.apple.servermgr_info.plist
/Library/Preferences/com.apple.servermgrd.plist
/Library/PrivilegedHelperTools/com.apple.serverd
/Library/Server
