Provide a way to search in multiple base DNs

In my ldap the users are located in DN=(ou=users,dc=example,dc=com), and service accounts in DN=(ou=sa,dc=example,dc=com). The size of LDAP is huge and it is crucial to limit the search scope to these org. units.
But I have the same entity to be retrieved from these ous:

@Entry(objectClasses = ["top", "person", "user"])
class LdapUser {
    @Id
    lateinit var id: Name

    @Attribute(name = "objectGUID", type = Attribute.Type.BINARY)
    lateinit var objectGUID: ByteArray
}

Therefore I have to perform the following code to search for the only record by objectGUID:

val ldapUser = ldapTemplate.find(
    query().base("ou=users").filter(guidFilter),
    LdapUser::class.java
).firstOrNull() ?: ldapTemplate.find(
    query().base("ou=sa").filter(guidFilter),
    LdapUser::class.java
).firstOrNull()

Please, provide a way to search multiple organizational units in one query.

Start with the ldapTemplate.find and query().base calls shown in the issue, then trace how search bases are represented and passed into one LDAP query. Done means the same LdapUser lookup can search both ou=users and ou=sa without issuing the two separate searches shown.
