The mailing list for listmasters using Sympa

[Warren Anderson <address@concealed>]

Hi,

I think one of the main reasons NOT to use sympa as a group management 
tool is the relative difficulty in leveraging your groups in other 
services. The large scientific collaboration I belong to (www.ligo.org) 
uses LDAP paired with Grouper. Grouper is extremely flexible for group 
management, can draw entities to group from an LDAP, and can then write 
group management information into LDAP (both by writinggroup entries 
into LDAP and by populating the multivalued isMemberOf attribute for 
the entities in a group). Very many tools have the ability to pull 
information out of LDAP without any modification (including sympa, 
which is what we do). For those tools that do not, whatever language 
they are written will almost surely have an LDAP module or library to 
make accessing the group information relatively straightforward to 
code. 

Perhaps your needs are not so varied, but we require groups for ACLs 
to several different brands of wiki, three different version control 
systems, three brands of bug/request tracking systems, posix/unix 
filesystems, grid computing (Globus) accounts, several in-house 
applications, web pages, mailing lists, etc. And to further complicate 
matters, our scientists use at least eight different linux distros, 
solaris, OS X, and at least three flavors of MS Windows. The amount 
of software we would have to write to leverage sympa groups for all of 
this would have been prohibitive. But as I say, your mileage may vary.

Cheers,
Warren
