For this we have added this part to Kernel/Config.pm file: ############################ LDAP ######################### # CustomerUser # (customer ldap backend and settings) $Self->{CustomerUser} = { Name => 'LDAP Lookup', Module => 'Kernel::System::CustomerUser::LDAP', Params => { # ldap host Host => 'domain.net', # ldap base dn BaseDN => 'OU=domain,DC=domain,DC=net', # search scope (one|sub) SSCOPE => 'sub', # The following is valid but would only be necessary if the # anonymous user does NOT have permission to read from the LDAP tree UserDN => 'CN=Israel Garcia Alvarez,OU=Sist,OU=Usuaris Roureda,OU=domain,DC=domain,DC=net', UserPw => 'Password', # in case you want to add always one filter to each ldap query, use # this option. e. g. AlwaysFilter => '(mail=*)' or AlwaysFilter => '(objectclass=user)' AlwaysFilter => '(objectclass=user)', # if both your frontend and your LDAP are unicode, use this: SourceCharset => 'utf-8', DestCharset => 'utf-8', # if your frontend is unicode and the charset of your # ldap server is iso-8859-1, use these options. # SourceCharset => 'iso-8859-1', # DestCharset => 'utf-8', # Net::LDAP new params (if needed - for more info see perldoc Net::LDAP) Params => { port => 389, timeout => 120, async => 0, version => 3, }, }, # customer unique id CustomerKey => 'uid', # customer # CustomerID => 'mail', CustomerUserListFields => ['cn', 'mail'], CustomerUserSearchFields => ['uid', 'cn', 'mail'], CustomerUserSearchPrefix => '', CustomerUserSearchSuffix => '*', CustomerUserSearchListLimit => 1, CustomerUserPostMasterSearchFields => ['mail'], CustomerUserNameFields => ['givenname', 'sn'], # show not own tickets in customer panel, CompanyTickets CustomerUserExcludePrimaryCustomerID => 0, # add an ldap filter for valid users (expert setting) # CustomerUserValidFilter => '(!(description=locked))', # administrator can't change customer preferences AdminSetPreferences => 0, # # cache time to live in sec. - cache any database queries # CacheTTL => 0, Map => [ # note: Login, Email and CustomerID are mandatory! # var, frontend, storage, shown (1=always,2=lite), required, storage-type, http-link, readonly [ 'UserTitle', 'Title', 'title', 1, 0, 'var', '', 0 ], [ 'UserFirstname', 'Firstname', 'givenname', 1, 1, 'var', '', 0 ], [ 'UserLastname', 'Lastname', 'sn', 1, 1, 'var', '', 0 ], [ 'UserLogin', 'Username', 'uid', 1, 1, 'var', '', 0 ], [ 'UserEmail', 'Email', 'mail', 1, 1, 'var', '', 0 ], [ 'UserCustomerID', 'CustomerID', 'mail', 0, 1, 'var', '', 0 ], # [ 'UserCustomerIDs', 'CustomerIDs', 'second_customer_ids', 1, 0, 'var', '', 0 ], [ 'UserPhone', 'Phone', 'telephonenumber', 1, 0, 'var', '', 0 ], [ 'UserAddress', 'Address', 'postaladdress', 1, 0, 'var', '', 0 ], [ 'UserComment', 'Comment', 'description', 1, 0, 'var', '', 0 ], ], }; ################ LDAP AUTH ##################### But when we access Customer web page ( See image attached) we see this error on Otrs's log: Feb 26 09:32:08 cmdbsrv OTRS-CGI-90[9463]: [Error][Kernel::System::CustomerUser::LDAP::CustomerSearch][Line:380]: Sizelimit exceeded Feb 26 09:32:08 cmdbsrv OTRS-CGI-90[9463]: [Error][Kernel::System::CustomerUser::LDAP::CustomerSearch][Line:380]: Sizelimit exceeded Feb 26 09:32:11 cmdbsrv OTRS-CGI-90[7443]: [Error][Kernel::System::CustomerUser::LDAP::CustomerSearch][Line:380]: Sizelimit exceeded Feb 26 09:32:11 cmdbsrv OTRS-CGI-90[7443]: [Error][Kernel::System::CustomerUser::LDAP::CustomerSearch][Line:380]: Sizelimit exceeded Does any of you have any idea why?
