There were some changes to schema between 1.2 and 1.3 I seem to recall to make it a bit better enforced, but could you check if schema syntax is enforced in your cn=config?

In theory its likely not an issue here (since utf8 is a superset of ia5), but in reality changing core schema like gecos is generally not a good idea beacuse it is hard for you to maintain that (since it's part of the rpms and will be upgraded and replaced). So it's likely to cause you more problems in the long run. (which is really unfortunate because schema historically in ldap is not considerate to other languages and cultures :( :( )

It's also unlikely we can change the rfc for gecos since the LDAP IETF group is effectively dead, and with little hope of revival.


I'd say your options are:

* Try to change the gecos schema, and to maintain that change forever
* optional; Submit an issue to 389-ds about changing it upstream, and we can discuss if we are willing to become rfc-divergent
* sanitise the data to be ia5 compliant IE remove accents etc.
* create a parallel schema like instituteGecos which is utf8 and migrate applications to use that

None of these options is really very attractive though I'm sorry :( It's a problematic situation for you I'm certain :(
