OpenVPN Segmentation Fault #14

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install openvpn 2.0.9
2. Install auth-ldap 2.0.3
3. Start openvpn with auth-ldap plugin. Pointing to auth-ldap.conf

What is the expected output? What do you see instead?
I expect to see the daemon running.

But I see...

Segmentation fault (core dumped)

What version of the product are you using? On what operating system?

2.0.3 on Mandrake 9.1 (Old i know, but everything compiled OK.)

Please provide any additional information below.

When i un-comment the line below openvpn loads.
# plugin /opt/auth-ldap/lib/openvpn-auth-ldap.so
/opt/auth-ldap/etc/auth-ldap.conf

I also tried it with a trailing cn=%u

My auth-ldap.conf

<LDAP
        URL         ldap://10.0.0.1
        BindDN      CN=tom,CN=Users,DC=pulla,DC=local
        Password    mypassword
        Timeout     15
        TLSEnable   no
</LDAP

<Authorization
        BaseDN          "DC=pulla,DC=local"
        SearchFilter    "(cn=%u)"
        RequireGroup    false
</Authorization

I turned openvpn verb to 11 but i cant see anything strange it just dies.
