is it possible to perform the deletion of only a certain number of

Hello Emmanuel, et al,
Indeed. I was using the ldapmodify man page as reference and it
doesn't mention the option of providing the value we wish to delete.
I wonder if it's also possible to use the same approach but for value
modification. In brief evaluation, my guess is no, since the ldif
syntax doesn't provide any way to distinct between the value to be
replaced and the one to replace with.
I don't understand your question. The 'modify' operation applied on an
AT allows you to do whatever you want, assuming you give it the right
operation to apply. 'replace' will discard all the values and replace
them by the new values. Otherwise, 'delete' deletes some specific
values, and 'add' adds the ones you provide.
Isn't it enough ?
Aye, i understand it can be done through delete/add. My wondering was
about the possibility to perform the change using a single operation.
It does. What the ldif snippet you gave just do is to replace all
'mailAlternateAddress' values by the two values you provided. Isn't it
what you wanted to do ?
In this case one would possibly have something like
But like i said, it doesn't make much sense.
Otherwise, assuming you want to replace the oldmail@ value by the
newmail@ value, the correct ldif would be :
Yes, that's what was intended.
Check the LDIF RFC (http://www.ietf.org/rfc/rfc2849.txt), you have
clear samples at the end.
Thanks for the pointer. I have visited the rfc before but didn't go
through the end of the document.
