AJAX connector from web to Activedirectory

We have few web based forms and we need to run a AJAX connector on local active directory to validate if the users alias/email address exists and have a Green symbol if exists or RED color symbol if it doesnt exists.
This will help us to validate from client end and save user time.
Can you please let me know if this is possible.

I haven't dealt with making an A/D call directly using AJAX, but you can certainly query A/D using your server-side language and return the result as json. Your AJAX connector would then just interact with the returned json object.

If you have a good relationship with your database team, you could request a special table that's populated by A/D and kept fresh using a scheduled job. One benefit to this approach is that it can be used on your intranet and public facing site without worrying about making calls to A/D. The caveat is that the DBAs would have to establish a linked server connection to A/D in order to keep your table populated.

Hi Lajuan,

we dont maintain a database for storing objects as the number of users are comparitively less. Howver we could store the user alias/SMTP in a csv/txt file. Is it possible to query ajax from web to the local csv.

Could you also share a sample code for the same.

Thank you so much.

@o365Adm - What server-side language are you using PHP, .NET, ColdFusion?

Do you have an automated way to keep the .csv/.txt file updated?

Hi Lajuan,

We use ASP with powershell. Yes we have an automated process to update the csv file.
LajuanTaylorCommented:
@o365Adm - Okay, one more thing. What A/D objects will your .csv file contain?

I don't need any data. Just the .csv file layout.
o365AdmAuthor Commented:
Sample format.
alias,smtp,UPN
xyz123,xyz@mydomain.com,xyz@upn.com
abc123,abc@mydomain.com,abc@upn.com
LajuanTaylorCommented:
@o365Adm - Just to confirm... You want a sample using classic ASP versus ASP.NET. Is that correct?
o365AdmAuthor Commented:
Correct. We are using classic ASP.

@o365Adm - Attached a zip file containing two possible solutions. You will have to remove the .txt from the asp and js files.

The JavaScript solution requires that you separate the A/D accounts into text files from a-z based on the first letter for each alias or search term.

The ASP option still requires that you pull the csv data into the getdata.asp file.

I think a better option might be to use XML or JSON as opposed to the csv. I didn't have time to test, but I know there's a current project that supports use of JSON with ASP:
