How to check whether an attribute is existing in an OU using JNDI

I want to check whether an attribute is exixting some where in a User URl. Right now I am doing like this. I am setthing the Returning attributes with this attribute and will do a search whic will return a naming enumeration. If the namingEnumeration is not null, then the attribute is valid. But this search will take some time to finish. So Is there any way to identify an attreibute is existing or not, without performanc hindrance
your suggestions will help
Thanks in advance

thanks for your advice,
I am only using the traditional if statement till now.So I don't know what makes you think I am expecting others to do my job. And also, I have been going through the forum, though the case may be that others want their job done by this forum members, that is not going to be the case with me, because here only to learn, not to travel on someone shoulders.!
Please be a bit patient and go through all the replies in the thread, before you go accusing the poster. Yeah, I can understand your position, you have nearly 2900 posts as such, but don't you think, it is somehow unfair when you go accusing someone without reading the replies.?
And I am not here to have argument with this forum members, because I know they do a great job helping the people with their doubts.
If u still want to argue, do it until you are satisfied.

  • How to check whether the Application Server directory exits or not

    Hi,
    I have a selection screen in which I give the Application server file name(UNIX file) as input. Here, I would like to check whether the Server directory exists or not.
    Let us say, the path I gave in the selection screen is /usr/sap/tmp/testfile.txt . Here, the file name is testfile.txt and the server directory is /usr/sap/tmp . I would like to check whether this directory /usr/sap/tmp exists in the server or not. I am not bothered about the file name as I am going to write data into the file. I am mainly concerned about whether the directory exists in the server or not. and one more thing... this is the Application Server path not the Local path.
    Can anyone help me on the same how to check whether the server directory exists or not.
    Thanks in advance.
    Best Regards,
    Pradeep.

    Also you can use the FM EPS_GET_DIRECTORY_LISTING for this purpose.
      Store the directory name
        l_dpath = p_file+0(l_no).
      Validate the directory of the application server
        CALL FUNCTION 'EPS_GET_DIRECTORY_LISTING'

    Hi Jogdand ,
    You can get the PO total value change form the PO business Object BUS2201 attribute  POTotalValueIncreased .
    Below code sample decribes how to get the BO attribute values
    1. INCLUDE <swfcntn01>.
    2. Create an instance of the BO by calling the macro and passing the three parameter.
        swf_create_object     <po bor object>     <BUS2201>     <po_guid>
    3. Get the PO attribute by calling macro
      swf_get_property   <po BOR object>   < 'POTotalValueIncreased' >    < lv_pototalvalueincreased>
    OR
    You can query the table BBP_PDHGP and get the original Value of the PO and call the FM BBP_PD_PO_GETDETAIL to get the new Value of the PO. Check the difference and if there is any difference then the PO value is changed.
    I hope this will be very useful.

  • Use Powershell to check whether and AD user exists

    We're trying to clean up roaming profile folders, and as part of the task I need to check whether the user actually exists in AD.  I have tried 3 different methods and so far none of them work.
    Either the empty result of the search doesn't equal $null (e.g. If ($objUser -eq $null) resolves to false) or Powershell crashes (like when I try to run that If statement).  So is there an AD User equivalent to Test-Path?
    RF

    I should add, if you want to use PowerShell filter syntax, you can use:
    $Name
    = "jsmith"
    $User = Get-ADUser
    -Filter {sAMAccountName
    -eq $Name}
    If ($User
    -eq $Null) {"User does not exist in AD"}
    Else {"User found in AD"}
    And if you only have PowerShell V1, you can use the following:
    $Name =
    "jsmith"
    $Searcher =
    [ADSISearcher]"(sAMAccountName=$Name)"
    $Results =
    $Searcher.FindOne()
    If ($Results
    -eq $Null) {"Users does not exist in AD"}
    Else {"User found in AD"}
    In all cases I assume you are checking the "pre-Windows 2000 logon" name, not the Common Name (the value of the cn attribute, which does not uniquely identify the object in AD).
