Network Login and Authentication
|
There are a large number of methods for Network Authentication, such as Samba/Windows Domain, NIS Domain, Kerberos, LDAP and Hesiod.
Unix and Linux systems have long had the ability to use NIS, Kerberos and LDAP, Windows has recently achieved this ability using Active Directory; however Microsoft have bastardised their Kerberos implementation so that it is non standard, probably in an attempt to prevent other systems from operating cleanly with their authentication systems. (This sort of thing has been done frequently by Microsoft with numerous International Standards, such as SMTP and IMAP) Linux is also able to use Samba to log into Windows Domains as a client, or to act and a Windows / Samba Domain Controller (PDC), the latest versions of Samba allows Linux systems to join Windows Domains as a peer.
|
As a result of NIS and samba being installed by default and these are probably the easiest to be used.
It is possible to get the imap to authenticate against a Windows Domain, this is done by entering the following file /etc/pam_smb.conf. This file contains two or three lines, the first line is the domain, the second and third lines contain the hostnames of servers that you wish to authenticate against. These hostnames must be resolveable. This will allow for example mail accounts or file shares to be authenticated against a windows domain.
There is a really useful piece of documentation to implement NIS here.
