Search Filters are not displaying any results when an NEW LDAP Directory is prioritized against the default JIRA Directory for LDAP integration purposes

We are currently integrating the LDAP direcotries into our JIRA server so we can maintain the list of users directly from LDAP
How3ever, during our POC activity, we encountered issues when trying to display several filters on the dashboards.
Most of these filters happen to have the account's username as a filter.

PLease note that the users in the LDAP Directory we are integrating already exists in the JIRA internal Directory
