Hi **Shihab**, We are here to help you and to help in a more efficient way, we need as much information as possible. If we understand well: You have two Gluu instance running and want to copy some attribute from one instance to another. > I click Validate button it says .. Which button are you talking about here? Please provide all information that you think is relevant.

Hi **Shihab**, Still need assistance?

Hi Shihab, Closing this ticket for inactivity. Feel free to reopen it when you want.

Sorry for the late reply. I was away for a couple of days. Here is the screenshot of the **Validate** button I was talking about. 

Hi **Shihab**, The first line of your ldiff file is this: ``` dn: inum=@!C6F1.6ADE.4777.2F1B!0001!3B73.1218!0005!9472,ou=attributes,o=@!C6F1.6ADE.4777.2F1B!0001!3B73.1218,o=gluu ``` Change this `o=@!C6F1.6ADE.4777.2F1B!0001!3B73.1218` to match the correct value. The import failed because there isn't an organisation with id `@!C6F1.6ADE.4777.2F1B!0001!3B73.1218` under `gluu` organisation on the instance where the import is apply. So you can use a ldap browser like `jxplorer` to find the right value for an organisation under `gluu` hierarchy. Bellow is an example: I want to import your ldif file in my Gluu instance. We my jxplorer i can see that the correct value is `@!619C.061B.1A7E.5AF4!0001!4377.CD0A`. Screenshot [here](https://pasteboard.co/HbZu5a9.png) So i change the first line of your ldif file to match my ldap structure like this. ``` dn: inum=@!C6F1.6ADE.4777.2F1B!0001!3B73.1218!0005!9472,ou=attributes,o=@!619C.061B.1A7E.5AF4!0001!4377.CD0A,o=gluu oxValidation: {"minLength":null,"maxLength":null,"regexp":""} gluuAttributeType: string description: The home publication of the user displayName: Home Publication gluuAttributeEditType: admin inum: @!C6F1.6ADE.4777.2F1B!0001!3B73.1218!0005!9472 gluuAttributeName: homePublication gluuAttributeOrigin: cuePerson oxAuthClaimName: homePublication oxSCIMCustomAttribute: true gluuSAML1URI: urn:gluu:dir:attribute-def:homePublication gluuStatus: active objectClass: top objectClass: gluuAttribute oxMultivaluedAttribute: false gluuSAML2URI: urn:oid:1.3.6.1.4.1.48710.1.3.1003 ``` And then import the modified ldif file. Hope that help. Thanks

Thanks for an elaborate answer. I will try that. By the way, it should documented [here](https://gluu.org/docs/ce/3.1.2/admin-guide/oxtrust-ui/#importexport-attribute-ldif).

That worked fine. Thanks again.
