Re: Significance of attribute names / alias

I'm trying to put together a schema that works for both Outlook and
Mozilla Thunderbird, as I haven't been able to find anything official or
complete.

I'm hitting a problem with a few fields where the two apps expect
different names.

For example, Outlook likes "URL" and Mozilla likes "workurl".

I have something like this in my schema:

attributetype ( 1.3.6.1.4.1.4203.666.100.124
        NAME ( 'URL' 'workUrl')
        EQUALITY caseIgnoreMatch
        SUP name )

If the NAME line is as above, Outlook can see the value, Mozilla can't.
If the NAME line is as below, Mozilla can see the value, Outlook can't.

        NAME ( 'workUrl' 'URL')

Is there a way to set up the attribute so that either name or alias is
equally valuable in a look-up ?


Hm, you've hit on a pet peeve of mine, so I'm going to rant for a second:

<rant>

Email clients should not define a schema for address book lookups, period. They should be configurable enough to allow users to assign address book values to whatever attributes the LDAP server they are querying. They should also allow the user be able to define the filter that will be used to search the directory. The only email client that I know of that will do this is Eudora, and as much as I don't like Eudora, it had the most thought put into its LDAP lookup design than of any other email client I've looked at.

</rant>

Back to your question, the almost same exact thing was asked a day or two ago about a different attribute. The answer lies in:

(From Howard Chu)
I'd agree that LDAP's design is deficient here. Certainly this problem does not happen with X.500 DAP. I believe that you can use the rewrite overlay and attribute mapping to handle this now. The relay backend may also be useful.
