Hi

actually we read in the sympa man page, that sympa supports dynamic mailing lists with LDAP. but i do not really understand what is meant by "dynamic maillist". the scenario is the following: i have an ldap server where all info (login, username, maillist subscription) is written in. i just want sympa to read the information ot of the ldap directory, when a mail is sent to a sympa maillist. sympa must not write into ldap.
the ldap_alias_management.pl script ( http://www.sympa.org/contrib.html ) seems to be a perlscript that has to be executed by a cronjob. it does not seem to be "dynamic".

No this script is lunched by sympa when some list are created or removed in order to receive incomming messages.

I think what you need is :

1)  configure lists in order to recover subscriber from your ldap directory. This is easy to do : create the list using the web interface. In the adminisrtation menu of the list, verify that the parameter 'user_data_source' is set to "include2' then create some data sources with all the needed LDAP parameters (host, port, baseDN, filter, ...) and set the TTL for update periodicity. Of course the LDAP server must be configured to accept queries from Sympa ; take care of the max number of answers parameter.
The process task_manager.pl will load Sympa cached datas as specified by your configuration (this cache is stored in sympa RDBMS backend). A list can use multiple external data sources. List owners can also be defined in the same way and you can configure the parameters ADD and SUB to decide if you accept or not some subscribers that are not listed in your LDAP directory.

2) configure sympa authentication in file 'auth.conf' in order to use your LDAP server as the authentication backend.

Both 'auth.conf 'and 'user_data_source' are documented in the reference manual.
