Kerberos Client Version E.1.6.2.09 Release Notes (5990-1526, January 2011)

• Support for TCP
Kerberos Client libraries can now use TCP to connect to the Key Distribution Center (KDC).
Libraries can use TCP to communicate with Microsoft KDCs (domain controllers) if they issue
tickets with excess PAC data.
• Administrators can now control the behavior of Kerberized login applications that call the
krb5_kuserok API provided by the libkrb5.sl library. In earlier versions of Kerberos
Client, krb5_kuserok checked the .k5login file in the user's home directory for access
permissions. This enabled users to modify the .k5login file and allow access to other users.
Administrators can now create files with the name .k5login.<username> in the /etc/
krb5/ directory. Administrators can also create symbolic links pointing to the .k5login file
in the user’s home directory. If the/etc/krb5 directory does not exist
krb5_kuserokcontinues to check the .k5login file in the user's home directory. If the/etc/
krb5/ directory exists, the krb5_kuserok API ignores any corresponding .k5login files
in the user's home directory while making authorization decisions. The format of the entries
in the new files in /etc/krb5 continues to be the same as that of the .k5login file in the
user's home directory.
