    Try to scan_ccache() after leash picks a cache
    
    We need to call scan_ccache() in order to notice that there
    are credentials and read their expire time.
    
    The call to scan_ccache() in the Leash case was inadvertently
    removed as part of commit 8651f3339ccc5a623172a8edfb9cf522883acacd.
    
    (cherry picked from commit 674f7d7abe2d4f8bc3fe791e4347a332e3ccfd41)
    
    ticket: 8012 (new)
    version_fixed: 1.12.3
    subject: gssapi.dll tries to get initial creds even when some are present
    status: resolved
