Update attributes on Full Managed accounts


We are currently using version 8.1.2

In our existing environment, Users can request for AD accounts via Web Portal. Post approval, appropriate Account definition is assigned to the identity and Full Managed AD account is created for the user.

Now, we have a requirement to update additional attribute (XYZ) on newly created AD account. 

- While submitting the account creation request in web portal, user will have an option to select if XYZ attribute needs to be enabled on AD Account once created.

Process ADS_PersonHasTSBAccountDef_Autocreate_ADSAccount/Contact is generated to create the account.

Can someone please let me know how can the attribute XYZ on ADSAccount table be updated.
