Hi All, In the servers we are unable to create LDAP connection over SSL(port 636). ADAM server has valid certificates under Computer\Personal folder. Network service has required permissions on the machine keys. Error details: ld = ldap_sslinit("tmachn1.dnsroot.biz", 636, 1); Error <0x0> = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, LDAP_VERSION3); Error <0x51> = ldap_connect(hLdap, NULL); Server error: <empty> Error <0x51>: Fail to connect to machn1.dnsroot.biz. 1220 error in event viewer. Error Details: Source: ADAM Category: LDAP instance LDAP over Secure Sockets Layer (SSL) will be unavailable at this time because the server was unable to obtain a certificate. Additional Data Error value: 8009030e No credentials are available in the security package This is causing login issues to SharePoint external users through ECTS. Certificates are ok. Your help will save me a lot. Please advice on this.

Hi V235, Thanks for posting here. > ADAM server has valid certificates under Computer\Personal folder. Network service has required permissions on the machine keys. How did you import the certificate to this domain controller host ? Please refer to Kurt L Hudson’s blog post and his TechNet wiki article and recheck your settings: Implementing LDAPS (LDAP over SSL) http://blogs.technet.com/b/pki/archive/2011/06/02/implementing-ldaps-ldap-over-ssl.aspx Thanks.

Hi Tiger Li, Thanks for reply... i got it resolved by clearing the old certificates and Installing the new certificate. ________ Regards Venkat
