I am getting this error when i try to run kadmin daemon.

kadmind[15257](Error): Cannot find/read stored master key while
initializing, aborting

when i tried to do kdb5_util create -s it says that

[root@bunty krb5kdc]# kdb5_util create -s
Loading random data
Initializing database '/var/kerberos/krb5kdc/principal' for realm 'VAM.ORG',
master key name 'K/M@VAM.ORG'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify:
create: File exists while creating database

It would be great if anybody corrects me.

Thank you,
