Chris, Running the debugger, I found out the DigestAuthenticator wants to use SHA-256. 8 months ago there was a change for RFC 7616. https://github.com/apache/tomcat/blob/9.0.74/java/org/apache/catalina/authenticator/DigestAuthenticator.java
To bypass the array of digest, I commented out some code so it was forced to use MD5 only. But In the RealmBase, I really don’t understand what getDigest is doing. When I create a MD5 digest, I use Username:Realm:Password. In the code it is using Nonce, nc, cnonce, gop…..

Thanks for double-checking both of those. I don't see anything in the changelog that seems like it would be related. Thing I suspect are related were in an earlier release. Are you able to run under a debugger, and are you comfortable doing that? It's pretty easy to set a breakpoint in the Realm and/or CredentialHandler to see what's being done when you try to authenticate. -chris > From: Christopher Schultz <ch...@christopherschultz.net> > Date: Friday, November 10, 2023 at 12:35 PM > To: users@tomcat.apache.org <users@tomcat.apache.org> > Subject: Re: CredentialHandler not working for MD5 > Peter, > > On 11/10/23 13:27, Peter Otto wrote: >> Logging into manager using MD5 works in 9.0.73 but now fails in >> 9.0.74->current >> Steps to reproduce. >> >> Step 1.
