Tom Poage commented on DIRSTUDIO-753:
-------------------------------------
Hi, Pierre-Arnaud.
With 2.0.0.v20120127:
Not a problem when using the Apache Directory Client API Provider.
Still a problem with the JNDI Provider (JRE 1.6.0_31 and 1.7.0_02).
Seems to be platform independent. I get the same behavior on Windows.
Thanks!
Tom.

> Key: DIRSTUDIO-753
> URL: https://issues.apache.org/jira/browse/DIRSTUDIO-753
> Project: Directory Studio
> Issue Type: Bug
> Components: studio-connection, studio-ldapbrowser
> Affects Versions: 1.5.3
> Environment: Linux (RHEL 6 x86_64)
> Reporter: Tom Poage
> Priority: Minor
>
> RFC 4512 (sec 5.1.2) suggests that an empty value in the rootDSE operational
> attribute namingContexts is normal, perhaps encouraged in some deployments.
> Some LDAP servers, such as recent versions of Sun/Oracle DSEE, can display
> namingContexts containing an empty value.
> I can't tell offhand if this is a bug with Directory Studio or JNDI. A
> sampling of other JNDI applications/code tested do not throw an exception on
> encountering the empty value.
> E.g.
> {code}
> ldapsearch -x -LLL -H ldap://myhost.example.org -b '' -s base 'objectClass=*'
> namingContexts
> {code}
> {noformat)
> dn:
> namingContexts: dc=example,dc=org
> namingContexts:
> namingContexts: dc=people,dc=example,dc=org
> {noformat}
> If an Apache Directory Studio Connection is set to the default of "Get base
> DNs from Root DSE", an exception is thrown on the empty value.

> Does it make sense for Directory Studio to ignore the empty value -- or at

> location?
