22 | * Password authentication, and Smartcard Authentication support are currently |
---|
23 | * available. All forms of authentication, current and future, should support |
---|
24 | * group, and attribute based restrictions; preference pulling; and group |
---|
25 | * syncronization. All forms of authentication should have basic support for |
---|
26 | * adding users, changing passwords, and updating preferences in LDAP. |
---|
27 | * |
---|
28 | * Password authentication has a number of configurations, including straight binds, |
---|
29 | * proxy based authentication, and anonymous-search based authentication. |
