Hi @Vinod Survase ,
I have found one article which was talking about the solution of the " Attribute Editor " tab in users properties is missing? Could you please check, if this helps your issue?
******Attribute Editor tab missing in Active Directory Users and Computers search********
Problem:
If you search for a user account, you don´t see the Attribute Editor tab in the properties of the user account.
First the „Advanced Features“ have to be activated in the “Active Directory Users and Computers” console. Just select View and click on Advanced Features.
Using a LDAP Query:
Right-click Saved Queries and click the New-Query option
Type in a name for your saved query, such as "Search SamAccount"
Click the Define Query button
Under the Find drop-down list, select Custom Search
Click the Advanced tab
Type in your query
(objectcategory=person)(samaccountname=tim.buntrock)
Using the group trick:
Search for a user
Click on the member of tab
Open a group from user
Close the user properties tab
Search for the user in the group member tab and double click him
Now you should see the Attribute Editor tab
Using Active Directory Administrative Center instead of ADUC
If you are using the AD Administrative Center you can directly access the Attribute Editor after a search.
