kerberosautoconfig(8) BSD System Manager's Manual kerberosautoconfig(8) NAME
kerberosautoconfig -- Kerberos -- Open Directory Single Sign On SYNOPSIS
kerberosautoconfig [-f directory_node] [-o output_dir] [-r realm_name -m master_kdc] [-u] [-k] [-v debug_level] DESCRIPTION
The kerberosautoconfig command creates / updates & removes the edu.mit.Kerberos file and the Kerberos:<REALM_NAME> config record in dslocal db from information stored in the Open Directory config record named KerberosClient. The existing edu.mit.Kerberos file is only replaced if the autogenerated header is present and the generation_id in the KerberosClient config record is greater than that within the file. The default location of the output file is /Library/Preferences/edu.mit.Kerberos. If the machine is standalone, this command will do nothing (unless the -u option is used). Definitions: directory_node An open directory node path specifier. Such as /LDAPv3/127.0.0.1 output_dir The directory in which kerberosautoconfig deposits the edu.mit.Kerberos file realm_name Name of the Kerberos realm that will be the default when creating a file from scratch master_kdc Host name of the master KDC for the default realm when creating a file from scratch debug_level Specifies the amount of debugging information printed to stdout, default is 1 Flags: -f Tells kerberosautoconfig to look in the specified open directory node for the KerberosClient config record. -o Specifies the directory in which kerberosautoconfig will write the new edu.mit.Kerberos file into -r kerberosautoconfig can create an edu.mit.Kerberos file from information passed on the command line. Use the -r and -m flags to spec- ify the default realm and master KDC for that realm. -m See above -k Adds the default Kerberos logging directives to the config file (useful when setting up a kdc) -u Forces an update of the file. Will overwrite an existing non-autogenerated edu.mit.Kerberos file. Use with caution. -v Specifies the amount of debugging information printed to stdout, default is 1 FILES
/Library/Preferences/edu.mit.Kerberos The main Kerberos config file (also known as krb5.conf on other systems) SEE ALSO
DirectoryService(1), Kerberos(1), kdcsetup(8), krb5.conf(5) BUGS
kerberosautoconfig looks for the KerberosClient config record in each of the open directory nodes on the search path. It merges the realm information from any KerberosClient config records it finds, but it only checks the generation_id from the first config record found. This means that the file does not get updated if the second KerberosClient record found changes. HISTORY
kerberosautoconfig first appeared in Mac OS X 10.3 Darwin June 2, 2019 Darwin
