I trying to implement LDAP authentication in C# Web Application.
I tried is using the below code.
try
{
using (LdapConnection conn = new LdapConnection(this.Server))
{
string uname = userName;
if (!string.IsNullOrEmpty(this.UsernamePrepend))
{
uname = string.Concat(this.UsernamePrepend, userName);
}
NetworkCredential cred = new NetworkCredential(uname, password, null);
conn.SessionOptions.SecureSocketLayer = true;
conn.SessionOptions.VerifyServerCertificate = (LdapConnection con, X509Certificate cer) => true;
conn.SessionOptions.ProtocolVersion = 3;
conn.AuthType = AuthType.Basic;
conn.Bind(cred);
}
}
catch (LdapException ldapException)
{
LdapException ex = ldapException;
if (!ex.ErrorCode.Equals(49))
{
this.LogError(ex, userName);
throw ex;
}
}
flag = true;
Every time I run it, it goes into catch block with exception LDAP server is unavailable.
Am I missing something?
Remove conn.SessionOptions.SecureSocketLayer = true;
