we created a custom attribute in Administration-managed custom attributes and now we are getting that attribute under customized information tab in user admin->identity management.
This attribute is coming for all users and it is working fine and I can give value to this attribute also.
Now the problem is we have more than 10000 users in the portal and we have to assign same value to this custom attribute to all the users.
Is there any possiblity of setting the value to all the user without coding.
If it is not possible then how can I proceed for coding.
any help will be appreciated.
