Xwin 32 not working

Dear All,

I have case where Xwin32 is not working in one of my server(RHEL5.10)

In one server its working, another server its not. All the setting a same.
And also with root accoungt i dont have any issue only with the user-ldap having the issue.

The difference see is the below, When I log in ..Xauthority file not getting created. Please help me to fix this.

Not working:

[root@Tes02v ~]# su - user-ldap
[user-ldap@Tes02v ~]$ logout

Working:

[root@Tes01v ~]# su - user-ldap
xauth: creating new authority file /home/user-ldap/.Xauthority
[user-ldap@Tes01v ~]$
