Powershell: Error HRESULT: 0x8007200B when adding a member to a group in AD (SOLVED)

[Fail Whale]

Hi

I am having a very weird problem with a script I am writing to create new users. Currently the user selects a group name from a drop-down list which is populated from AD. The cn of the group and the Distinguished Name of the newly created user are passed to a function to add the group membership.

This works perfectly for most groups unless the name contains a hypen or underscore without spaces ie.
GroupName = Works
Group - Name = works
Group-Name = Fails
Group _ Name = Works
Group_Name = Fails
Group Name_2 = Fails
Group Name-2 = Fails

The code for the function in question is:

Code:

FUNCTION AddGroups ($UserDN, $Group)
{
#Create Group DN
Write-Host $Group
$GroupResults = SearchAD "group" "LDAP://OU=London,DC=MYCOMPANY,DC=LOCAL"
FOREACH ($objResult in $GroupResults)
    {
    $objItem = $objResult.Properties
    
    IF ($objItem.cn -ccontains $Group)
        {
        $GroupDN = $objItem.distinguishedname
        }
    }
#Add User to Group
$UserAD = [ADSI]"LDAP://$UserDN"
$Member = $UserAD.distinguishedName
Write-Host $Member
$GroupAD = [ADSI]"LDAP://$GroupDN"
Write-Host $GroupAD.distinguishedName
$GroupAD.member.add("$Member")
$GroupAD.setinfo()
}

The problem seems to be is when one of the problem group names is selected it stops the $UserDN variable being passed correctly so If I insert a couple of write-hosts for trouble shooting I am able to retrieve
$GroupAD.distinguishedName but not $UserAD.distinguishedName. Anyone got any Ideas what might cause this as I am completely stumped now.

Any use to you?

Quote:To create a variable name that includes a hyphen, enclose the
variable name in braces. The following command creates a variable
named "save-items".

C:\PS> ${save-items} = "a", "b", "c"
C:\PS>${save-items}
a
b
c

Unfortunately not, it is only the content of the variable which contain hyphens not the variable names.

I have tried the same code outside of the function on the problem groups and it does work. The issue seems to be with passing the variables to the function.

If it helps this is the code which loads the Function, but there is not much to it

Code:

#add the new user to each group selected on the form
FOREACH ($selection in $clbAdGroups.SelectedItems)
    {
    AddGroups $UserDN $selection
    }

I think this time we may have a winner or at least a step in the right direction:

Quote:There is one small caveat when using query variables to provide tab completion:

- Many LDAP attribute names defined in AD schema have a hyphen ‘-’ in them. Since .NET property names cannot have a hyphen, I have modified the script to convert hypens ‘-’into underscores ‘_’. Thus, for writing a filter using attribute “msDS-LastKnownRDN”, you would have to use $xADUser.msDS_LastKnownRDN.

Get-ADObject -filter { $xADObject.msDS_LastKnownRDN -like "*" } -IncludeDeletedObjects

Enjoy!

Unfortunately again no luck. In the problem I am having underscores are causing the same problem as hyphens and only when they are not enclosed by spaces.

I think I need to wrap the variable content in some sort of brace or quote marks but cant find anything especially as hyphens and quotes should not be escape characters.

Finally got this solved. The Function the data was originally coming from was returning too much data to the variable, which I have cleaned up now. Was just manifesting in a very strange way.

hmmm that explains why I could find no mention of the _ underscore issue lol nice find
