Authentication failure ticket is ineligible for postdating
Each time a user logs on, the system retrieves the SID for that user from the database and places it in the access token for that user.The system uses the SID in the access token to identify the user in all subsequent interactions with Windows security.[logging] default = FILE:/var/log/krb5kdc = FILE:/var/log/krb5admin_server = FILE:/var/log/[libdefaults] default_realm = EDMONSON. NET dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h forwardable = yes default_tgs_enctypes = DES-CBC-CRC DES-CBC-MD5 RC4-HMAC default_tkt_enctypes = DES-CBC-CRC DES-CBC-MD5 RC4-HMAC preferred_enctypes = DES-CBC-CRC DES-CBC-MD5 RC4-HMAC [realms] EDMONSON. Now if you are planning on give your users home folders you need to make their directories. The easiest way to do that is to just reboot the machine, since sometimes there might be users with files open and you can’t unmount while that is going on.Note A security identifier (SID) is a unique value of variable length used to identify a trustee (security principal).Each account has a unique SID that is issued by an authority, such as an Active Directory domain controller, and stored in a security database.Also, it is assumed that your website SSL Certificate(s) (Server Certificate) along with matching Root Certificate(s) (CA Certificate) are installed on the Net Scaler(s) properly. It is your responsibilities backup your Net Scalers configuration before making any changes for recovery if needed.

The Kerberos model is based in part on Needham and Schroeder's trusted third-party authentication protocol and on modifications suggested by Denning and Sacco.
Kerberos performs authentication as a trusted third-party authentication service by using conventional (shared secret key1) cryptography.
Kerberos provides a means of verifying the identities of principals, without relying on authentication by the host operating system, without basing trust on host addresses, without requiring physical Secret and private are often used interchangeably in the literature.
Version 4 is publicly available, and has seen wide use across the Internet.
Version 5 (described in this document) has evolved from Version 4 based on new requirements and desires for features not available in Version 4.
