Attribute modification
You can modify attributes that are associated with a directory entry. To modify an attribute, use Web Administration Tool or the command line.
Not all schema changes are allowed. See Disallowed schema changes for change restrictions.
Any part of a definition can be changed before you add entries
that use the attribute. After the entries that use the attribute are
added, you can use the edit procedure to change the indexing rules
and to increase the size of the attribute length. You can also change
to enable multiple values.
Note: You can disable multiple values only
if the existing entries are single-valued. You cannot disable the
multi-value option if any of the existing entries are multi-valued.
Use
either of the following methods to edit an attribute. Web
Administration Tool is the preferred method.
