Well you know something I didnt use ADfind but your example did point me in the right direction. <br />
<br />
I was able to test this using find, custom search in ADUC. Modified your syntax a little bit to below<br />
<br />
(objectcategory=group)(!ms<wbr />ExchRequir<wbr />eAuthToSen<wbr />dTo=TRUE)(<wbr />mailnickna<wbr />me=*)<br />
<br />
And it in fact does return a list of distribution groups where authentication is not turned on. <br />
<br />
Thanks

<div class="content wysiwyg-content">
So I am trying to find all of the distribution groups that are in my AD environment that allow unauthenticated users to send to them. <br />
<br />
In another question I was directed to the following LDAP query<br />
(&amp;(objectClass=group)(!msE<wbr />xchRequire<wbr />AuthToSend<wbr />To=TRUE))<br />
This query will return all distribution groups that dont require authentication.<br />
<br />
This seems to work OK except it returns extra results. I am only interested in email enable distribution groups. I was able to come up with a query to find these. <br />
(&amp;(&amp;(&amp; (mailnickname=*) (| (objectCategory=group) ))))<br />
<br />
What I would like to know is how can I combine these two queries so that they will only return mail enabled groups that dont require authentication?

Help combining two LDAP queries

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
