Subject: [PATCH 09/12] Issue 4972 - gecos with IA5 introduces a compatibility
9f2552
 issue with previous (#4981)
9f2552
9f2552
releases where it was DirectoryString
9f2552
9f2552
Bug description:
9f2552
       For years 'gecos' was DirectoryString (UTF8), with #50933 it was restricted to IA5 (ascii)
9f2552
       https://github.com/389ds/389-ds-base/commit/0683bcde1b667b6d0ca6e8d1ef605f17c51ea2f7#
9f2552
9f2552
       IA5 definition conforms rfc2307 but is a problem for existing deployments
9f2552
       where entries can have 'gecos' attribute value with UTF8.
9f2552
9f2552
Fix description:
9f2552
       Revert the definition to of 'gecos' being Directory String
9f2552
9f2552
       Additional fix to make test_replica_backup_and_restore more
9f2552
       robust to CI
