krb5.conf.k5login.directory
Use this policy to specify an alternative location for user .k5login files.
If specified, this string value will be used for the k5login_directory in the [libdefaults] stanza in krb5.conf and the user's .k5login file will be named as <k5login_directory>/<unix_name>.
For security reasons the specified directory should be owned by root and writeable by root only. If the directory does not exist, adclient will create it.
