We use an old LDAP for authenticating users. But the email addresses stored in this LDAP will be out of use in a few weeks. Because we are migrating to a cloud hosting of Jira, we will continue the use of this old LDAP till the migration. So we want the accounts to use a new email address. But at every login, this field is changed to the LDAP-value.
Is it possible to stop the update of the email address from LDAP every time a users logins?
