In the context of LDAP, when alterations need to be specified to an entry, the “changetype: modify” keyword is used in the LDIF file. This keyword indicates that modifications are to be made to the existing LDAP entry. The modify operation can be used to add, replace, or delete attributes and their values. The syntax of the modify operation is as follows:

changetype: modify add: attribute attribute: valuereplace: attribute attribute: valuedelete: attribute attribute: value

Each modify operation is separated by a hyphen (-) and a blank line separates different entries. The attribute;binary subtype can be used to indicate that the attribute values are binary data. The LDIF syntax for reading a binary value from a file is:

attribute;binary:< file:///path/to/file
