I don't know am i right or wrong but I have a confusion with the option " credit-till-time=jan/01/1970 00:00:00 credit"

How Can I fix it. I did try with system clock setting but date is ok there . Can anybody tell me what is dst option on system clock ?

subscriber=admin username="monalisa" password="1234" pool-name="pppoe" last-seen=never credit-count=1
credit-left=4w2d credit-duration=4w2d credit-price=600 credit-till-time=jan/01/1970 00:00:00 credit-time-added=4w2d

When the user first logs in the credit-till-time will change to the time what is has left.

About the error message - User manager doesn't support MSCHAP and MSCHPv2, it supports only PAP and CHAP.

First of all , I f I uninstall the 9.23 version of user manager and upload the new 9.24 packege and reboot the router then nothing heappens . I mean router doen’t show any package .I have tried so many times but it didn’t work .
After that I was trying with the older package and
I have activated PAP authentication in the client machine for my pppoe server . I can login into the pppoe server only if I have a secret into the pppoe profile but user manager doesn't show any usage for that account . And if I add any customer from the web interface of user manager then I can't even login into the user manager with the newly created customer login name. But if I create any user from the command line then I can login from the web interface. I don't know what am I missing . I have ticked to use radius into the pppoe profile and also ticked to accept request from the radius . I have used the router local ip 10.0.0.1 and also with the public ip and the secret correctly and have also tried with the 127.0.0.1 IP. Then what am I missing . .

My pppoe server and the usermanager is running on the same machine . Then what the hell am I missing??????

Can anybody please help me out to get it done ???????????????????????

I will be waiting to hear from somebody ….

Thanks

This fixed my problem. I just changed the settings in my pppoe server.

Yup, by unchecking the mschap and mschap2, i was able to authenticate a pptp session from (radius) user-manager.

I am concerned tho as to the security ramifications, as PAP will be sending out the authentication details in plain text right? So anyone sniffing the network can see the authentication details, and then later on, use this to connect via the vpn to the internal net right?

Spent a couple of hours solving this issue. Now everything works. But i think it's very bad that VPN connection goes without any encryption. Future versions of RouterOS should include user manager with MS-CHAP encryption.

I agree, is there any plans for these protocols in future userman releases?

Yes, we will add them, but in future. There are still lot of other things to do for the User Manager.

Finally i was able to configure pptp with userman auth, is it possible to limit 1 user within 1 session using userman? because the value of ppp user profile property "only-one" is ignored when using RADIUS auth.

Thankyou
