Dear all, I posted this problem a week ago after searching in posted and solved emails like here ( http://www.mail-archive.com/search?q=rlm_ldap&l=freeradius-users@lists.cistr... ). I have already asked but the answers were not effective... Anyway, I d like to express my gratitude to those who have tried to read and respond to my problems ! So I m asking myself if : Using LDAP with freeradius is it something new or something? My problem is about the ldap library for freeradius (libldap which is needed by rlm_ldap) ... What should I do to install and configure it 'cause it's not in the freeradius-server package(I rebuilt it 5 times and I paid attention to the output? If I ll receive the same answers I received before then maybe the problem is in my operating system(CentOsV5.3) Thanks to all ... Best regards ... NB: I am fed up of this buuuuuuuuuuuuug!
