Getting ATT_OR_VALUE_EXISTS from AD server when updating values against, error, test

amy

Hi,
We are using the latest version of Spring LDAP against an AD server. I am unable to re-produce this in a unit test (I tried updating with the same value and a different value as well).

Sometimes we are seeing this when our code is running in production. We are trying to set a value against the ipPhone attribute in a user record (it may or may not be a different value) and we get this error back from AD.

Please adviseCode:
