Subject: RE: Salted SHA1 Hash
You asked the same question not far back, and were provided with a tool to
handle this.
Simply put, JtR 'proper' splits up the lines, due to the ':' chars. There
are several ways to attack this. You can use the --field-separator-char=c
flag for JtR (I would not recommend this because of other side effect). You
can use dyna 24, but convert the salt to $HEX$. This is the route I would
take, personally.
This message provided a tool to convert to easily convert dyna to $HEX$
format:

I am going to get that tool tied into normal JtR build/tool chain.
Jim.
