在MOSS2010中使用SSO

  在MOSS2007中，微软提供了SSO服务，但在2010中您可能没那么容易的找到相应的东西。实际上，在2010里，SSO已经被改为SSS(Secure Store Service).

 下边是2010中的Get/Set credentials的实现: (具体的配置google一下)

 

   private  SecureString toSecureString(string sourceString)
        {
            SecureString secure = new SecureString();
            foreach (char c in sourceString.ToCharArray())
            {
                secure.AppendChar(c);
            }
            return secure;
        }

        public override void SetCredentials(string[] userInfo)
        {
            try
            {

                List<SecureStoreCredential> creds = new List<SecureStoreCredential>();

                SecureStoreCredential name = new SecureStoreCredential(toSecureString(userInfo[0]), SecureStoreCredentialType.UserName);
                SecureStoreCredential pwd = new SecureStoreCredential(toSecureString(userInfo[1]), SecureStoreCredentialType.Password);
                SecureStoreCredential dm = new SecureStoreCredential(toSecureString(userInfo[2]), SecureStoreCredentialType.Generic);
                SecureStoreCredential reps = new SecureStoreCredential(toSecureString(userInfo[3]), SecureStoreCredentialType.Generic);

                creds.Add(name);
                creds.Add(pwd);
                creds.Add(dm);
                creds.Add(reps);

                SecureStoreCredentialCollection credes = new SecureStoreCredentialCollection(creds.ToArray());

                SecureStoreServiceProxy proxySs = new SecureStoreServiceProxy();
                SPServiceContext context = SPServiceContext.GetContext(HttpContext.Current);
                ISecureStore store = proxySs.GetSecureStore(context);
                store.SetCredentials(ApplicationName, credes);
            }
            catch (Exception ex)
            {
                LogUtility.Instance.Error("SSOMOSS2010-SetCredentials failed. " + ex.ToString());
                throw;
            }
        }

        public override string[] GetCredentials()
        {

            string[] nullArr = new string[4];
            try
            {
                string[] strRet = new string[4];

                SPServiceContext context = SPServiceContext.GetContext(HttpContext.Current);
                SecureStoreProvider providerSs = new SecureStoreProvider();
                providerSs.Context = context;
                SecureStoreCredentialCollection creds = providerSs.GetCredentials(ApplicationName);

                if (creds.Count != strRet.Length)
                {
                    LogUtility.Instance.Error("The moss sso configuration is incorrect.");
                    return nullArr;
                }

                for (int i = 0; i < creds.Count; i++)
                {
                    IntPtr ptr = System.Runtime.InteropServices.Marshal.SecureStringToBSTR(creds[i].Credential);
                    string sDecrypString = System.Runtime.InteropServices.Marshal.PtrToStringUni(ptr);
                    strRet[i] = sDecrypString;
                }

                return strRet;
            }
            catch (Exception ex)
            {
                LogUtility.Instance.Error("SSOMOSS2010-GetCredentials failed. " + ex.ToString());
                return nullArr;
            }
        }
