I've been experimenting with LDAP and Cosign login plugins for WordPress. Most of them are out of date and are more or less incompatible with WordPress v.3.5. Usually the first error that comes up is
Notice: has_cap was called with an argument that is deprecated since version 2.0!All this means is that instead of using the numerical role identifier argument in a function that adds a menu or submenu, the required capability should be used instead.

For example, in the Simple LDAP Login plugin, the number 10 in a function that creates a settings submenu:
add_options_page("Simple LDAP Login", "Simple LDAP Login", 10, "simple-ldap-login", "simpleldap_menu");needed to be replaced with
add_options_page("Simple LDAP Login", "Simple LDAP Login", create_users, "simple-ldap-login", "simpleldap_menu");within a function that requires administrator or Super Admin privileges to run.
This does mean that you need to figure out what capability the user needs to be allowed to see the menu or submenu in question.
Roles and Capabilities are listed here in the WordPress Codex
