Re: Exception is showing in nifi UI users page
There is no file that contains this mapping, the users and groups are periodically loaded from LDAP into memory on each nifi node. The id of each user and group is a UUID that is seeded from the corresponding name. UUID.nameUUIDFromBytes(seed.getBytes(StandardCharsets.UTF_8)).toString(); For a group, "seed" would be the group name.

Re: Exception is showing in nifi UI users page
Yes Mat, But i cant upgrading nifi till next 2 months. As i am not able to add user so its a blocker. Thats why asking u how the AD group name from the authoriser file is mapped to group identifier of authorization.xml file. Any place where we are storing this maping? So that i can delete it from authorization.xml Any other workaround is there. Thanks, Sanjeet On Fri, 6 Mar 2020, 7:24 pm Matt Gilman, wrote: > I would recommend upgrading.

Re: Exception is showing in nifi UI users page
I would recommend upgrading. If I recall correctly, there were actually a couple of JIRAs addressing different but similar issues dealing with users or groups being removed from a directory server. Even if you could identify and remove the problematic entries, you could possibly hit this again if another user or group were removed later.

Re: Exception is showing in nifi UI users page
Hi , The AD group names are present in Authoriser.xml file, In authorisation.xml file the group identifier (unique id) is present inside policy identifier tag. So could you please help me to understand where AD group name in authoriser.xml file and group identifier in authorisation.xml map together. So that i can delete it in authoriser.xml file.
