Re: How to modify a single attribute from multiple list of attributes

[Tom Leach <leach@coas.oregonstate.edu>]

Thanks to everyone who replied.  In my searching, I hadn't found any 
examples of modifying an attribute that had multiple values.  the 
following ldif did exactly what I needed:
    dn: cn=config,o=dhcp
    changetype: modify
    delete: dhcpStatements
    dhcpStatements: log-facility local7
    -
    add: dhcpStatements
    dhcpStatements: log-facility local3

I was stuck on trying to use 'replace' rather then 'delete + add' and I 
couldn't find an ldif syntax that worked.

Thanks again!
