Errors When Using WebCenter Spaces Functionalities to Queries Users/Groups (Doc ID 1364280.1)

Last updated on SEPTEMBER 25, 2023

Applies to:

Oracle WebCenter Portal - Version and later
Information in this document applies to any platform.


WebCenter (WC) Spaces is displaying some errors when trying to query users/groups. Those users and groups come from an Open LDAP authentication provider mapping to IDM Lotus Note LDAP server that is configured on the Domain. Users from LDAP are able to Sign In normally, apparently without any issues.

WC Spaces is configured to use users and groups that come from an OpenLDAP (based on IBM Domino LDAP server). Users and groups can be seen on the WLS Console and users can Sign In in WC Spaces apparently without issues.

However some of the WC Spaces functionality are not working correctly and some very nasty errors are registered into WC SPaces logs:

1- Users cannot use People Connections to invite other to users. When they call the task flow to search for user to connect with, nothing happens and error are generated in the logs.
2- When setting users/groups membership to the Spaces, can search for users and assign them to the Space, but cannot do it for Groups. When trying to query a group to add it to space, get some errors logged:
