When using CSDATA attribute as explained in article 275795 I am getting error:
modification failed: RAC Dispatcher Modify failed: <attribute name>: attribute type undefined
Missing entries in slapd.conf.
All custom fields have to be properly defined in slapd.conf
For Troubleshooting purposes:
Work with Mainframe team to enable debug while reproducing this use case (attempting to modify attribute):
* Replace LDAPR151 with your STC name in #1 and #3
Output can be shared with IM support for analysis if error is different.
