Question OpenLDAP and Invalid Credentials

[enrique]

Hi all,

This is my first post in this forum.

I'm using the LDAPTest function below to authenticate users accounts from OpenLDAP, and get Invalid Credentials exception despite of working with Softerra LDAP Browse.

I need you to help me see what else I can check. Where to see.

Regards,

Enrique.

Function LDAPTest(ByVal strUser As String, ByVal strPassword As String) As Boolean

    Dim bolAuthenticated As Boolean = False


    Dim strLdapServer As String = "ldap.server.com"
    Dim intLdapPort As Integer = 389

    Dim strLdapUserIdField As String = "cn"
    Dim strLdapUserDomain As String = "ou=People,dc=server,dc=com"

    Dim oldapDirectoryIdentifier As New LdapDirectoryIdentifier(strLdapServer, intLdapPort, True, False)


    Dim oldapNetworkCredential As New NetworkCredential(strUserFCD, strPassword)


    Dim oldapLdapConnection As New LdapConnection(oldapDirectoryIdentifier, oldapNetworkCredential, AuthType.Basic)


    oldapLdapConnection.SessionOptions.ProtocolVersion = intLdapProtocolVersion

        bolAuthenticated = True
        LogError("Usuario v?lido!", Nothing)

        If lex.ErrorCode = 49 Then
            bolAuthenticated = False
            LogError("Usuario inv?lido:" & strUserFCD, lex)
        Else
