  • 1.  LDAPS User Data Import - UBA App

    Posted Tue June 06, 2023 08:14 AM

    Hi everyone,

    I was trying to do LDAPS user import through QRadar UBA app and it runs into an internal server error.

    In the error log it was detected as a "Socket connection timeout". Trying to find out the root cause for the issue. Appreciate your help on this.

    Hi Dushan, is this a QRadar or QRoC installation? If it is a QRoC installation, did you create a Data Gateway Proxy Mapping? LDAPS uses Port 636, did you check the certificate and the FW settings for Port 636?

    Hi Reisman,

    Thanks for the response. 

    This is QRadar on premise distributed architecture with a separate app host. Firewall settings were confirmed and port 636 is enabled in both ways.

    Hi Dushan,

    Did you get this issue resolved? If not I would suggest try taking a wireshark capture and look at which end is resetting the connection. It's either the cert/ciphers or tcp port issue. UBA uses fips certified ciphers so it could be SSL ciphers are not getting negotiated.

    Regards,

    Prince
