LDAP Problems

Fernando Jose P de Souz — Sun, 07 Dec 2008 23:45:45 GMT

Hi,

I would like to authenticate in my HP-UX 11.23 windows users.
AD Server: Windows 2003 Server
Domain: ldap.teste
user: teste1

Output of commands and files in attach.

Wait

Fernando.

################################################################
# This sample file will authenticate the user who belongs to #
# either Kerberos or Unix system. Using this configuration file#
# if the user is authenticated through Kerberos then the Unix #
# authentication will not be invoked. However,if the Kerberos #
# authentication fails for the user, then the fallback #
# authentication mechanism PAM-Unix will be invoked to #
# authenticate the user.The assumption is the user is either #
# present in Kerberos or in Unix system. #
# #
# In case, the administrator wants the password for all the #
# users to be synchronous between Kerberos and Unix systems, #
# then the control flag should to be set to "required" for all #
# the entries with use_first_pass option set for pam_unix. #
# If password synchronization is optional then try_first_pass #
# option need to be set for pam_unix, so that the user can #
# login using the appropriate passwords. #
# #
# The module pam_hpsec(5) is stacked as mandatory module above #
# all the modules for making security checks before #
# authentication. #

Fernando,
Did you get feedback on this issue? I am facing a similar problem and I am interested in a possible solution.

Hi Fernando

http://forums13.itrc.hp.com/service/forums/questionanswer.do?threadId=1381465

The above link contains links to manuals, a cookbook whitepaper on setting it up, notes on Kerberos / pam configuration, and notes about Windows (release, rights and so on).

Might be of use.

Thanks,
Johnson
