KRB5_ANAME_TO_LOCALNAME(3) UNIX Programmer's Manual KRB5_ANAME_TO_LOCALNAME(3)

NAME

     krb5_aname_to_localname - converts a principal to a system local name.

LIBRARY

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

     krb5_boolean
     krb5_aname_to_localname(krb5_context context, krb5_const_principal name,
             size_t lnsize, char *lname)

DESCRIPTION

     This function takes a principal name, verifies its in the local realm
     (using krb5_get_default_realms()) and then returns the local name of the
     principal.

     If name isn't in one of the local realms and error is returned.

     If size (lnsize) of the local name (lname) is to small, an error is re-
     turned.

     krb5_aname_to_localname() should only be use by application that imple-
     ments protocols that doesn't transport the login name and thus needs to
     convert a principal to a local name.

     Protocols should be designed so that the it autheticates using Kerberos,
     send over the login name and then verifies in the principal that authen-
     ticated is allowed to login and the login name.  A way to check if a user
     is allowed to login is using the function krb5_kuserok().
