ERROR : u'Microsoft OLE DB Service Components', u'The parameter is incorrect.'

Hi, I am trying to pull the users from Active directory but when i am using adquery module gives me the following error *Traceback (most recent call last): File "", line 1, in File "", line 3, in Open File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 282, in ApplyTypes result = self.oleobj.InvokeTypes((dispid, LCID, wFlags, retType, argTypes) + args) pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'Microsoft OLE DB Service Components', u'The parameter is incorrect.', None, 0, -21470 24809), None) and this was causing because of the statement self.__adodb_conn.Open("Provider=ADSDSOObject")** line no 38 file adquery.py(version pyad-master 0.5.15)

so, i tried by line by line code from the interpretor and replaced self.__adodb_conn.Open("ADSDSOObject") of line 38(above) then it is working fine but i havent seen this problem in pyad-0.5.14.tar.gz version , I am able to create object to the ADQuery class as shown below *>>> from pyad import

qobj = adquery.ADQuery()**

Now that I look at this I'm kinda surprised that anything is passed into open. What happens if you call it with no connection string? i.e., self.__adodb_conn.Open() or self.__adodb_conn.Open("")? Given that there are no options to be set, it seems that it should be called without any option.

Yes, you are right, when I set the default username and password then it is working fine with the both self.__adodb_conn.Open() or self.__adodb_conn.Open(""), if I didnt set the default values it shows the error as below **

Yeah that makes sense---provider isn't set when uid /pwd isn't provided until that line. I'll change the open to be empty when uid and pwd are provided and push out a new version of the egg. thanks for your help troubleshooting.

I get the same problem when install pyad from pip install . I try to keep setting like that self.__adodb_conn.Open("") , but still doesnt work . I have default username and password set by command pyad.set_defaults(ldap_server="", username="", password="") . Please help me check this. I using version 0.5.16

I don't have much to add to the convo at this time, but I'm getting this on version 0.5.16 as well.

Figured it out-- At line 38 in adquery.py, the Open() function had "Provider=ADSDSOObject" as it's parameter.

Changing the parameter to "" allowed the code to continue as normal.

From:

    def __init__(self, options={}):
        self.__adodb_conn = win32com.client.Dispatch("ADODB.Connection")
        if self.default_username and self.default_password:
            self.__adodb_conn.Provider = u"ADsDSOObject"
            self.__adodb_conn.Properties("User ID").Value = self.default_username
            self.__adodb_conn.Properties("Password").Value = self.default_password
            adsi_flag = ADQuery.ADS_SECURE_AUTHENTICATION | \
                            ADQuery.ADS_USE_ENCRYPTION
            self.__adodb_conn.Properties("ADSI Flag").Value = adsi_flag
            self.__adodb_conn.Properties("Encrypt Password").Value = True
            self.__adodb_conn.Open("Provider=ADSDSOObject")
        else:
            self.__adodb_conn.Open("Provider=ADSDSOObject")

        self.reset()

To:

    def __init__(self, options={}):
        self.__adodb_conn = win32com.client.Dispatch("ADODB.Connection")
        if self.default_username and self.default_password:
            self.__adodb_conn.Provider = u"ADsDSOObject"
            self.__adodb_conn.Properties("User ID").Value = self.default_username
            self.__adodb_conn.Properties("Password").Value = self.default_password
            adsi_flag = ADQuery.ADS_SECURE_AUTHENTICATION | \
                            ADQuery.ADS_USE_ENCRYPTION
            self.__adodb_conn.Properties("ADSI Flag").Value = adsi_flag
            self.__adodb_conn.Properties("Encrypt Password").Value = True
            self.__adodb_conn.Open("")
        else:
            self.__adodb_conn.Open("Provider=ADSDSOObject")

        self.reset()

EDIT: To be clear, the solution is the same as above, but for some reason in this version the problem appears to be un-fixed.
