SSH Reference Manual
can not add/read/manipulate entries for associated aliases. In other words, a Guardian or alias user can 
add/manipulate entries for that Guardian or alias user only.  
The value LOGINNAME is recommended if different people are using the various aliases configured with the 
same Guardian user identifier.  
GUARDIANNAME 
The default owner is the Guardian user identifier, independent if the logon name is an alias or a Guardian user. 
Entries are read using the Guardian user ID only. This means that a Guardian user can add/read/manipulate 
entries for associated alias users, and vice versa.  
The assumption is that the same person uses the aliases of a Guardian user identifier and the Guardian user 
identifier itself. This was the default before this enhancement was introduced (in release 89) and therefore value 
GUARDIANNAME needs to be used if the client mode policy of previous releases should be kept.  
BOTH 
The default owner is the login name but a guardian user can add or manipulate entries stored under an alias or a 
guardian user identifier. Entries are read for both the login name and the guardian user in case these are 
different (entries of the alias are read first, then entries of the guardian id). The value BOTH is only 
recommended if a guardian user and all aliases configured for this guardian user are solely used by one person 
and client mode records are to be stored under Guardian user identifier as well as alias names.  
Example: Assume, an alias entry is present, but not an entry for the associated Guardian ID, and the user is 
logged on as the alias. With client mode owner policy set to LOGINNAME, privileges to read/alter the entry 
would be granted, for GUARDIANNAME they would not be granted because a matching entry is not found, 
and for BOTH they would be granted. If the Guardian entry is present but not the alias, and the user is logged 
on as the alias, LOGINNAME access would not be allowed, GUARDIANNAME would be allowed, and BOTH 
would also be allowed.  
Considerations 
•  The value (list of authentication methods) is only relevant for outgoing ssh connections. For incoming 
connections the list of authentication methods is configured for each user (attribute ALLOWED-
AUTHENTICATIONS).  
•  The authentication methods actually allowed at the client side consist of those methods that are specified in the 
client side option "AllowedAuthentications" as well as in the value of SSH2 parameter 
CLIENTALLOWEDAUTHENTICATIONS.  
Default 
The default value is BOTH.
