Hello,

interesting, is the ldap server running on same server? Is the connection via local network?

When starting as service, kamailio is probably run under user kamailio. Any firewall in place or system restrictions for user 'kamailio'?

You can change the user/group for kamailio service in /etc/default/kamailio

Cheers,
Daniel

Hi Daniel,
thank you very much for your quick reply. Yes I can connect to ldap and make search from kamailio if I start the kamailio with command line in a terminal ("# kamctl start" or "#kamailio") as root.It fail to connect to ldap only when I start it as service from the boot or I run the command "service kamailio start".

Best Regards,
Peng

Hello,

the first error I could spot related to ldap is:

Jun 21 10:28:41 kamailio3p1 /usr/sbin/kamailio[8786]: ERROR: ldap [ldap_connect.c:166]: [sipaccounts]: ldap bind failed: Can't contact LDAP server

suggesting connectivity problem to ldap server. Is it running? Can you connect to ldap server from a terminal?

Cheers,
Daniel

Hi,
we try to use LDAP module in kamailio, first we try only load the ldap.so only to see if it can be loaded. When we start from the command line with either "kamctl start" or directly "kamilio", the kamailio is started normally with different children. When I try to start as service with "service kamailio start" or "/etc/init.d/kamailio start". It fails with the following error in the /var/log/messages:

Without ldap.so loaded, we can start the kamailio as a service normally with "service kamailio start".
The platform running kamailio is: RHEL5.6_X64


Can you help us please? Because we want to start the kamailio as a service from the boot


Thanks a lot in advanced!

Laura
