-------------------------------------------------------------------

For instance, a loaded {{OpenLDAP}} schema will have this {{MatchingRule}} :

{noformat}
( 2.5.13.10 NAME 'numericStringSubstringsMatch' SYNTAX 1.3.6.1.4.1.1466.115.121.1.58 )
{noformat}

but the associated syntax ({{1.3.6.1.4.1.1466.115.121.1.58}}) is not present in the schema...

>                 URL: https://issues.apache.org/jira/browse/DIRAPI-320
>             Project: Directory Client API
>          Issue Type: Bug
>    Affects Versions: 2.0.0.AM2
>            Reporter: Pavel Zlámal
>            Priority: Minor
>
> When I use _JarLdifSchemaLoader_ it seems to load _userPassword_ attribute type with
different Comparator than when I load it from LDAP connection (openLDAP in my case).
> Then If I call:
> {code:java}
> Objects.equals(val, attribute.get())
> {code}
> to check if value passed to my method is the first in the attribute, I get _ClassCastException_,
since it tries to pass _String_ (normalized value) to the _ByteArrayComparator._
> When I use Schema only loaded from connection, then it works, since it uses _ComparableComparator._
> {code:java}
> java.lang.ClassCastException: java.lang.String cannot be cast to [B
>     at org.apache.directory.api.ldap.model.schema.comparators.ByteArrayComparator.compare(ByteArrayComparator.java:32)
>     at org.apache.directory.api.ldap.model.entry.Value.equals(Value.java:1389)
>     at java.util.Objects.equals(Objects.java:59)
> {code}
> So there is probably bug in schema ldif included in JAR or in equals() implementation
of Value.
