      Description

      Have a Crowd application where user names contain spaces or other non-URL safe characters.
      Try to use this Crowd Application to authenticate and authorize into Nexus. This will not work because the REST call made to the crowd server will form a non-safe URL that is not encoded properly.

      This is what you see in logs when you try to map a "user name" user id into Nexus:

      Similar exceptions occur if you try to map a Crowd group and then authenticate the user "user name".

      Possible Workarounds

      • use user ids that do not contain non-url safe characters
      • use the LDAP realm instead which does not use REST API and properly escapes the relevant LDAP queries
