other informat:
if I logon with root and create one folder the name as username in home direcotry, e.g /home/bylong , bylong is a username.
and change owner by issuing command # chown bylong /home/bylong
then everything is ok.
thus, I guess there are something wrong with
/etc/pam.d/common-session file
Code:
#session required pam_unix2.so
#session optional pam_umask.so
session sufficient pam_unix2.so
session sufficient pam_ldap.so
#session optional pam_umask.so
session required pam_mkhomedir.so skel=/etc/skel umask=0077
system seems did not invoke pam_makhomedir.so to create user home folder when user fisrt logon.
what 's that reason? many thanks in advance!
