In my Active Directory users are contained in two different organisation units:  
OU=users, **OU=unit-01** ,DC=example,DC=com  
OU=users, **OU=unit-02** ,DC=example,DC=com

How can I set both base\_dn values with condition "OR" to option:  
`xpack.security.authc.realms.ldap.example.user_search.base_dn:`

to search for a user in unit-01 and, if the result fails, search for a user in unit-02?
