using LDAPS query in powershell

Question

using LDAPS query in powershell

shashidhar joliholi 291

Hi Team,

We are using following powershell cmdlets to get user info.

$AccountName = "Shashidhar.Joliholi"
$Query = "(&(objectClass=user)(objectCategory=person)(samAccountName=$AccountName))"
$UserInfo = Get-ADUser -LDAPFilter $Query

We are planning to block LDAP and go with LDAPS in DCs. does it impact above powershell script. if yes, what modification need to be done on the powershell cmdlets to use LDAPS to get $UserInfo.

can i use $UserInfo = Get-ADUser -LDAPFilter $Query -server dc.domain.com:636 ?

Need your help!

Thanks,
Shashidhar Joliholi

Out of interest how are you planning to block the use of LDAP and what changes are you planning to make so clients only connect on LDAPS/636?

Hi @shashidhar joliholi ,

No matter if you are using LDAP or LDAPS the query will always remain the same. The only difference is that the LDAP communication gets encrypted when using LDAPS.
You don't need to change anything regarding the query.

Hope I was able to answer your question.

Hi Stoyan,

Thanks for the comments. we are using -LDAPfilter to use LDAP queries in the powershell Get-ADUser. if we block LDAP
does -LDAPfilter works with LDAPS. ? or i need to modify anything in the script to communicate through LDAPS.

$UserInfo = Get-ADUser -LDAPFilter $Query -server dc.domain.com:636 ? do it works ?

Thanks,

Hi Shashidhar,

yes, as already mentioned the only thing that changes with using LDAPs are the encrypted connection and also the port (like seen in your command).
You can find another exmaple here:

What is important of course is that all your domain controllers are configured for ldaps, meaning tehy have the required certificate.

You can test the ldaps connectivity to your DCs, using the function here:

Hope this clarifies it.
