The number of tool maintainers should be just below 1000 at the moment; the number of tools seems to match up roughly (not sure where the extra 13 directories come from, though).

valhallasw@tools-bastion-03:/home$ ls | wc -l
967
valhallasw@tools-bastion-03:/data/project$ ls | wc -l
1511

However, @Krenair measured more tool maintainers:

krenair@bastion-01:~$ ldapsearch -x cn=tools | grep member: -c
1063

which might mean we have almost a hundred users that never got so far to actually log in?

And a third number:

tools-bastion-02.tools:~
bd808$ ldapsearch -LLL -x cn=project-tools|grep 'member: '|wc -l
1225

I guess the next mystery to solve here is which of cn=project-tools,ou=groups,dc=wikimedia,dc=org and cn=tools,ou=projects,dc=wikimedia,dc=org is the actual membership roster of the tools project.

I think it's the former, see T138150

cn=project-tools,ou=groups,dc=wikimedia,dc=org is the one I had picked at some point during Striker development as well. I of course didn't make any notes about why I chose that one. I'll be documenting the LDAP layout as maintained by OpenStackManager soon as I start figuring out how account creation works.

Change 307960 had a related patch set uploaded (by BryanDavis):
Count members of tools project, not all posix users

Great, that'd be T138151 :)
