Created: 23/Oct/25 16:27
Priority: cid:jira-generated-image-static-critical-704f2786-9eae-4d58-adef-0c2aaea1db17 Critical
Reporter: Clemens Robbenhaar
Description:

If any of the group mappign lookup faisl, login via LDAP is no longer possible.

The error message actually does not show up in the log, until the level for the Logger org.xwiki.contrib.ldap has been set to debug.

Without that only a "Authentication failure with login [UserXY]" is logged, but the login fails anyway.
