151448 - Strings with non ASCII characters from MS Active Directory LDAP aren't searchable and displayable

Status: NEW

(MailNews Core :: LDAP Integration, defect)

Description

[Tom Mraz]

I see this in the Address book LDAP all the time. We use MS Active Directory on
Windows 2000 as a LDAP server. I can't search names using accented characters
and when I use email address for searching (we have simple rule for name->email)
there is no name shown in the search results if it contains accented characters.

What charset is Active Directory storing and returning its characters in?  I
_thought_ AD supported LDAPv3, which would imply UTF8, but maybe not.

Do you have any idea, how can I find it out?

I spent some time to organize global addressbooks using openLDAP and also
noticed problems with "international characters".

One way to see this:

- Create an entry into Mozilla Addressbook. 
- Export addressbook using LDIF format.
- add new record using openLDAP, using new entry from exported LDIF file
- retrieve same record using Mozilla LDAP browser(?) and compare it to any MS
Exchange or MS Outlook LDAP browser.

Another way:
- use mimencode to get BASE64 version of string containing non-ASCII characters.
- add base64 string into ldif file
- use openldap to update LDAP database
- retrieve record using Mozilla, MSE or MSO.

IMHO this is quite serious problem because some LDAP fields are used both for MS
and Mozilla and this way non-ASCII characters cannot be used for these fields.

Alternative solution (ugly one):  #119291, and then use separate LDAP fields
fields for MS and Mozilla addressbooks.

This bug is still alive in
Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.7b) Gecko/20040316

may be, it stops even Mozilla?

Is there any 'public' LDAP server with which I can test this issue? According to
comment #3, this is not just just MS Active Directory, right?

Change OS All from comment 4.

Comment 7

[Dan Mosedale (:dmosedale, :dmose)]

For anyone seeing this bug, what character set is your AD server storing its data in?
