Alioth needs to generate an index.aux file.  It'd be helpful if we had
an example script for doing this.  Here's the script used for
git.infradead.org (MIT licence, says its author):

--- cut ---
#!/bin/sh

cd /home
for a in * ; do [ -r $a/public_git ] && [ ! -d /home/git/users/$a ] && ln -s /home/$a/public_git /home/git/users/$a ; done

cd /home/git
find . -name 'HEAD' | grep ^[-./=+a-zA-Z0-9]*\$ | sed s:/HEAD\$:: | while read DIR ; do
        TREEUID=`stat -c %U $DIR`
        TREEUSERNAME=`grep ^$TREEUID: /etc/passwd | cut -f5 -d: | sed s/\ /+/`
        if [ "$TREEUSERNAME" = "" ]; then
                TREEUSERNAME=$TREEUID
        fi
        echo $DIR $TREEUSERNAME | sed s:/:%2F:g
done > /home/git/.index.aux.$$

mv /home/git/.index.aux.$$ /home/git/.index.aux

--- cut ---

I suspect Alioth wants something like (untested ...)

cd /srv/git.debian.org/git
ls */*/HEAD | grep ^[-./=+a-zA-Z0-9]*\$ | sed s:/HEAD\$:: | while read DIR ; do
        TREEUID=`stat -c %U $DIR`
        TREEUSERNAME=`XXX`
        if [ "$TREEUSERNAME" = "" ]; then
                TREEUSERNAME=$TREEUID
        fi
        echo $DIR $TREEUSERNAME | sed s:/:%2F:g
done > /srv/git.debian.org/.index.aux.$$

mv /srv/git.debian.org/.index.aux.$$ /srv/git.debian.org/.index.aux

where XXX would be how to turn a username into the name of a user.
I dunno how Alioth works; ldap or postgres db seem plausible answers.
