    It looks like there is an issue with the keys found in the Kerberos keytab. The Kerberos keytab should be encrypted will all types, so it is possible that the defaults for the encryption are not set on the account side.

    Here another link that might help you with the same:

    Hello Foussenik,

    Could you please tell how the Kerberos is working on the Mobile devices?
