Authentication LDAP

[andersonserra]

Hi friends,

I use OTRS system a long time, but now, I want connect via LDAP protocol... I am having a problem about authentication via LDAP.

Take look my file configuration /opt/otrs/Kernel/Config.pm

# DatabaseHost
# (The database host.)
$Self->{DatabaseHost} = 'localhost';
# Database
# (The database name.)
$Self->{Database} = 'otrs';
# DatabaseUser
# (The database user.)
$Self->{DatabaseUser} = 'otrs';
# DatabasePw
# (The password of database user. You also can use bin/otrs.CryptPassword.pl
# for crypted passwords.)
$Self->{DatabasePw} = 'my_code_DB_postgresql';
# DatabaseDSN
# (The database DSN for MySQL ==> more: "man DBD::mysql")
# $Self->{DatabaseDSN} = "DBI:mysql:database=$Self->{Database};host=$Self->{DatabaseHost};";

# (The database DSN for PostgreSQL ==> more: "man DBD::Pg")
# if you want to use a local socket connection
$Self->{DatabaseDSN} = "DBI:Pg:dbname=$Self->{Database};";
# if you want to use a tcpip connection
$Self->{DatabaseDSN} = "DBI:Pg:dbname=$Self->{Database};host=$Self->{DatabaseHost};";


$Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP';
$Self->{'AuthModule::LDAP::Host'} = 'localhost';
$Self->{'AuthModule::LDAP::BaseDN'} = 'dc=localhost,dc=com';
$Self->{'AuthModule::LDAP::UID1'} = 'uid';

$Self->{'AuthModule::LDAP::SearchUserDN'} = 'cn=admin,dc=localhost,dc=com';
$Self->{'AuthModule::LDAP::SearchUserPw'} = 'my_code_ldap';

this is my sample of my configuration file Config.pm....

I see that I loss access in system... I took look in movie... http://www.youtube.com/watch?v=ZwODnB5L5lM

I'd like know how can I connect through database and ldap account? Because I want to ensure connection redundancy, in other words I desire keep both connections working!

I am looking forward to response.... Thanks in advance!

Concepts similarly apply to agent backends.

hi crythias,

thanks for help. I'd like to know, if is there some schema of entires for OTRS to insert to file ldap.conf?...

Thanks.

No schema. It assumes you know your schema and can read it. If you know the keys/labels for your fields, you tell OTRS what it needs to request when it authenticates.

Hey friend!

I got it, I understood how it works... it queries the uidNumber of users, but you need add memberUID object in group that the user participates. after several attemps I found a way for it works. Below follow my example configuration. hugs
