Lsyncd Permission denied (publickey,password) - ssh

Question

I am setting up lsyncd at for automatic sync local and remote folders. I have researched for many solution available, also adding extra params to the conf file.
I have also, updated the sshd_config with PermitRootLogin without-password
Also, I am able to ssh with password and also rsync without password manually tried but the problem is when I use it via lsyncd it give permission denied error 3 times and exit (seems like its asking for password).
lsyncd.conf.lua file
settings {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/log/lsyncd/lsyncd.status",
statusInterval = 10
}
sync {
default.rsync,
source="/home/gaurav/Desktop/source/",
target="root#xxx.xxx.xx.xxx:/root/destination/",
rsync = {
compress = true,
acls = true,
verbose = true,
_extra = {"-P", "-e", "/usr/bin/ssh -p 22 -i /home/gaurav/.ssh/id_rsa -o StrictHostKeyChecking=no"}
}
}
Also tried with this one also.
settings = {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/log/lsyncd/lsyncd.status"
}
sync {
default.rsyncssh,
source = "/home/gaurav/Desktop/source/",
host = "xxx.xxx.xx.xxx",
targetdir = "/root/destination/"
}

If you are using ubuntu 12.04 you must use rsyncOps instead rsync = {} block.
Try this:
sync {
default.rsync,
source="/var/www/",
target=server..":/var/www/",
excludeFrom="/etc/lsyncd/lsyncd-excludes.txt",
rsyncOps={"-e", "/usr/bin/ssh -o StrictHostKeyChecking=no", "-avz"}
}
