Unable to update person(Employee) data after modifying LDAP user account

To confirm are you updating the LDAP account from the target system or within Manager? 

Hi Troy,
I am trying to update Employee record which is linked to LDAP user account, using both the options Target System and Manager. 

Thanks in advanced 

For linked and managed user accounts, the data flow is defined from the identity to the user account (LDAP in your case), One Identity Manager acts as master for these properties if you will.

If you the LDAP user account to act as master, you would need to implement a custom process similar to the one for AD user accounts called "ADS_ADSAccount_Update_UpdatePerson".

Hi Markus Weiss-Ehlers, Thank you for the suggestion. 

I have implemented custom process and Script by referring "ADS_ADSAccount_Update_UpdatePerson". It is running successfully, I am not getting expected results. 
If you can help me here, It will be grateful.  

I am sorry, but the forum is not the place to help you to debug your solution in such detail. I kindly suggest checking the professional services offerings from one of our partners or from One Identity itself if you need more detailed assistance.
