OMG so this is a project with some History: started in mid-90's, then I left ISP job and gave it to another guy, then Jeroen changed job too and the project was half-abandoned, so I decided to take it back. Now, refactoring C code written over the course of 20 years is... real fun although I must admit back in 90's I avoided quite a lot of typical C pitfalls - no CVEs so far even though it's relatively popular in some circles https://github.com/kravietz/pam_tacplus
