* auth/ldap: fix login errors
This fixes 2 ldap auth login errors
* Missing entity alias attribute value
* Vault relies on case insensitive user attribute keys for mapping user
attributes to entity alias metadata. This sets the appropriate
configs in the cap library.
* ldap group search anonymous bind regression
* Anonymous group searches can be rejected by some LDAP servers if
they contain a userDN. This sets the configs in the cap library to
specify unauthenticated binds for anonymous group searches should
exclude a DN.
