[krbdev.mit.edu #1264] authentification problem

[MEHDI SEBBANE via RT]

hi there,

Well, I have a serious problem and I really need your help. I'm a graduate
student at Al-akhawayn University, an Americain university in Morocco.I
have as a project for my security course to deploy Kerberos.
  After the installation and running the servers krb5kdc & kadmind,
setting the database & adding principles to it, I wanted to check if it
works.  I found that:
* when I try to log in (frm a kerberos client) as an Admin it gives me the
following msg "Decrypt integrity check failed"

the problem is that I have to give my the report of a working project
before Wednesday. Can you please help me solve this. by the way,I'm
working on a redhat platform.

thank you so much
best regards

M.Sebbane
