Signing an export

Steps

To digitally sign the data during an export to an output LDIF file, run the export-ldif tool with the –sign option.

Example:

The following command runs an offline export of the userRoot backend and signs the content when written to an output file called data.ldif.
```
$ bin/export-ldif --backendID userRoot \
  --ldifFile /path/to/data.ldif --sign
```
