Unable to update the ssh keys

Hi all,

I am wondering why its not accepting the password of the icinga user from the remote host.

steps on server:

  1. su - icinga
  2. ssh-kegen

steps on client:
3)useradd icinga
4)passwd icinga

steps on server
icingaserver: ssh-copy-id -i ~/.ssh/id_rsa.pub icinga@client-------> asks password
when i give password of icinga it doesnot take for some reason and i always get error – authentication failure

though the password is correctly issued.

Please suggset
