-----------------------------------

we use radius authentication on this openBSD server as workaround, 
because for openBSD no pam-(ldap) is available. here, all users, mail, 
ftp, yni are authenticated against openldap using various authentication 
methods (pam-ldap, pure ldap, courier-authlib with ldap, pure-ftpd with 
ldap, ...).

the ldap-accounting-schemas we use are posixAccount and 
qmailControl/qmailUser. No radius schema so far.

the radius authentication works fine, as far as password checking is 
concerned. The following radius-daemon output shows the login of a user 
cvs into the system.

----------------------

BUT when this user is logged in, it has the following parameters:

cvs at myhost -> id
uid=10001(cvs) gid=102(users) groups=102(users)
cvs at myhost ->

all these id-parameters are from the local /etc/master.passwd file and 
not from the ldap directory.

instead of (when logging in to the user cvs on a different server) i get 
the following (correct) id-parameters

cvs at yourhost ~> id
uid=1067(cvs) gid=100(users) groups=100(users),503(release2)
cvs at yourhost ~>

when i check the ldap-host log, i see, that not even an attempt is made 
to request session parameters from the ldap server.

what do i where need to change?

thanks for any advice
