If +that file does not exist, all principals with a first component +identical to the username, and a realm considered local, are allowed +access. .Pp -Then -.Nm -checks if principal is the same as user@realm in any of the default -realms. If that is the case, +The +.Pa .k5login +file must contain one principal per line, be owned by +.Fa user , +and not be writable by group or other (but must be readable by +anyone). +.Pp +Note that if the file exists, no implicit access rights are given to +.Fa user Ns @ Ns Aq localrealm . +.Pp +Optionally, a set of files may be put in +.Pa ~/.k5login.d ( Ns +a directory), in which case they will all be checked in the same +manner as +.Pa .k5login . +The files may be called anything, but files starting with a hash +.Dq ( # ) , +or ending with a tilde +.Dq ( ~ ) +are ignored. Subdirectories are not traversed. Note that this +directory may not be checked by other implementations. +.Sh RETURN VALUES .Nm returns -.Dv TRUE . -.Pp -After that it reads the file -.Pa .k5login -(if it exists) in the users home directory and checks if -.Fa principal -is in the file. -If it does exists, .Dv TRUE -is returned. -If neither of the above turns out to be true, -.DV FALSE -is returned. -.Pp +if access should be granted, +.Dv FALSE +otherwise. +.Sh HISTORY The -.Pa .k5login -should contain one principal per line. +.Pa ~/.k5login.d +feature appeared in Heimdal 0.7. .Sh SEE ALSO .Xr krb5_get_default_realms 3 , .Xr krb5_verify_user 3 , .Xr krb5_verify_user_lrealm 3 , -.Xr krb5_verify_user_opt 3, +.Xr krb5_verify_user_opt 3 , .Xr krb5.conf 5 -- cgit v1.1
