After login to ubuntu, whenever I try to change any settings it gives authentication attempt failed error.. But when I tried to change the password using recovery mode it gave authentication token manipulation error..?? Can anybody help me with this issue??

First Enable super user account password on Ubuntu

set a password for root user as shown below.

$ sudo passwd root
[sudo] password for ramesh:
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

Now with the new password you can login as super user with su command

$ su -
Password:
#

now you try that what ever you want its access it. but if this also not working must comment me ....:)
