kerberos error

[Moorthi Pongiannan]

Hi

I am working on the AD (Windows 2008 R2==> DC1/DC2) with Linux clients
(Redhat 5.5) integration using LDAP and kerberos. Everything works fine
except one issue. When I change the password while DC1 is down, I am geting
the following error. Does anyone come across this issue?

Nov 11 12:41:23 broadlab54 passwd: pam_krb5[5475]: password change failed
for test at KCLAB.COM: Requested protocol version not supported

and gets following error in the command prompt but I can login using the new
password.

Password: Authentication token manipulation error

Thanks, Moorthi
