I have problems with synchronisation Confluence with Crowd. Confluence accepts only part of groups, for the rest of them it writes in log:
WARN [scheduler_Worker-4] [atlassian.crowd.directory.DbCachingRemoteChangeOperations] logFailures Could not add the following entity to the directory [ Crowd Internal Directory ]: Some-Group-Name
There is no "{" in the group names, only alphanumeric, spaces, "-" or "_".
When I create new copy of crowd directory and activate it instead of the existing one, the set of groups affected by the issue, is a little bit different.
