SAML with SSL VPN Issues

[aalvarezj]

Hello,

I have a #Fortigate 100F with v7.0.12 and I have a issue with VPNSSL + Azure SAML

I configured it in others Fortigate with no problem, but in the last i can't connect with Forticlient, it stops in 40% when i try to connect.

I have enabled debug and i see this error:

__samld_sp_login_resp [842]: Failed to process response message. ret=-111(Failed to verify signature.)
samld_send_common_reply [114]: Code: 1, id: 576, data_len: 56
samld_send_common_reply [122]: Attr: 21, 8,
samld_send_common_reply [122]: Attr: 22, 32, Failed to verify signature.

Can someone helps me to find the problem?

Thanks, regards

Hello @aalvarezj ,

Thank you for reaching out. 

This error in SAML debugs generally points to an issue with the certificate used in the SAML communication.

Can you try to re import the SAML certificate and test again ?
