14.5.9 Renaming Calendar Users

If one or more user ID's need to be changed, run the csrename utility.

This utility performs the following steps:

• Converts the user ID's in the Calendar Server LDAP attributes (the ones with the ics prefix). The LDAP directory is updated in place.

• Renames the users in events and tasks on the Calendar Server database files. It writes the new database to a destination directory. Existing database files are not modified.

Be aware that changing even one user ID causes the whole database to be rewritten. So this is a “costly” utility to run.

For further information on the csrename utility, see Appendix D, Calendar Server Command-Line Utilities Reference.
