Hi all, I have checked through the form but nothing has seemed to explain what is going wrong. Here is the log to start:

This just occurs with AD Users which validate properly within the GUI. Local users connect normally without issue. 

Auth Method is setup with Local and Group AD

Router Log just shows this

This is a USG 40 running 4.32. Something similar is also occurring on a USG 20 - VPN

Server is 2012 R2 in both cases.

    Hi @Thysmith,

     

    AD user is able to establish SSL VPN to USG40.


    Make sure ad-users is in selected user in SSL VPN policy.


    If you’re using the default Authentication Method rule, make sure “group ad” is on the list.


    If you create another rule(ex: new_auth) in Authentication Method with “group ad”, remember to select the new created rule (ex: new_auth) in CONFIGURATION > System > WWW > Service Control > Authentication.


    The latest firmware is sent to you in the private message. 
    If AD user is still unable to build SSL VPN, please feel free to let me know and send the remote access information to me via private message.

    I'm also having a similar issue, running firmware V4.32(ABAQ.0) on USG20-VPN
    Is there a newer firmware?\

    Hi Emily, Some of my users are still having quite a bit issues connecting. The new firmware you provided did have good results but it is still hit and miss, any other suggestions?

    @Thysmith
    Regarding to your description, some of users faced the issue, others did not.
    You may check issue account on device.
    Go to AAA server, and press test.

    If the account is in the AD group, the result will show as below

    Or you need to make sure the account already added in your own AD server.

    Haha, that is definitely not the issue.

    What I am seeing is this:

    I am actually now trying it with a Local User Account (Nick and a Domain account NickW)

    They both show as logged in on this page of the router. 

    BUT

    Aint Nobody home. 

    I get this but nothing else in the logs 


    (hope you can see that)

    It Appears that 4.33 dropped today and I noticed SE 4.0.3.0. So far things worked right after reboot, but I will test further and report back.
