There's the today answer (use password authentication) and there's the todo answer (this should not have errored, and probably should not have failed). LDAP authentication as implemented in DSpace uses a username/password pair so, if this isn't working, it's probably broken rather than impossible. The result is an NPE, which IMHO is always an indicator of code that needs fixing. The site of the NPE from the stack trace should suggest how we came to be setting attributes on a nonexistent request. Although it seems fairly obvious: 'o.d.sword.SWORDAuthenticator.authenticates' passes a null 'HttpServletRequest' to 'AuthenticationService.authenticate', and that service would pass it on down to 'LDAPAuthentication.authenticate' if so configured. (Noted in passing: there's another class o.d.sword.SWORDAuthentication with an identically named method, which class seems to be used nowhere in DSpace.) We need a Github Issue for this. It's probably best if it comes from someone who's actually observed the problem and can provide logs. > On Tuesday, June 4, 2024 at 11:27:39 AM UTC-5 Joyner Library wrote: > Hi All, > > We have enabled sword version 1 in the local configuration but haven't > changed other sword settings.
