Hello there,

I am now progressing - i think. but got stucked. I enabled the ldap plugin. radiusd -X display all the correct info. but when try to connect vpn from windows client. here is the error i get. Maybe you guys have some tips on it.

GRE: read(fd=6,buffer=611860,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logs

it seems i need some lines in my dictonary.microsoft file for pppd. How do i add this ? all I am trying to do here is pppd to delegate ip pool for client and radius to authentication for user via ldap. where I am missing thing ?

Any help would be appreciated.

Thanks guys, I should have search for it :) I configured the ldap section that fits to my environment. Now, how to load this ldap module in radiusd.conf file so it will use ldap authentication ? also where can i add the redundant ldap server in the ldap module ? sorry for too many my early beginners questions.

you installed via package manager? you've probably got a freeradius-ldap
