Important missing points: the classes used in XxxSecurityRealm.groovy used for building the beans.
I am investigating whether this effort is feasible.
Thanks Jesse Glick Please let me know if I can be of any assistance.
Rob Winch thanks for the offer! I think I am past the stage where I struggled to find Spring Security 5 equivalents to various Acegi Security idioms that could not be resolved by a simple fix of imports (could not find a clear Rosetta stone except for the 3 → 4 migration). If you can spare any time, by all means skim over the running changes to Jenkins core and comment if you notice any clear abuses of the API. The work going forward will be dealing with compatibility from plugins. There is a draft overview of the effort for background.
Rob Winch actually, you could be of assistance if you have any time to spare: I have been struggling in https://github.com/jenkinsci/ldap-plugin/pull/49 to find the Spring Security equivalents of a number of Acegi Security API calls relating to LDAP, not made any easier by the fact that I know little about LDAP itself.
I have filed a JEP draft for this whole effort.
