Hi
you're having a nullPointerException when you import the user "samruddhas".
This may be caused by an empty mandatory field in LDAP.
It seems that it doesn't import your user and it leaves the screen name empty, so when you try to authenticate, it fails.
If I were you I would check my LDAP User Mapping variables, the mapping between ldap fields and liferay fields
Regards
Juan Fernández

I have checked that all required attributes (Screen Name, Password, Email Address, First Name, and Last Name) present in LDAP and also seen that this user successfully imported into liferay database but when he tried to login into liferay it giving blank page with above mention exception.

Thanks in Advance !!

what is your LDAP server?

See if setting the following parameter to "false" helps. As the description states this will not allow the changes made in Liferay to sync with your LDAP server.

#
# Settings for exporting users from the portal to LDAP. This allows a user
# to modify his first name, last name, etc. in the portal and have that
# change get pushed to the LDAP server. This will only be active if the
# property "ldap.auth.enabled" is also set to true. New users and groups
# will be created at the specified DN.
#
ldap.export.enabled=true

It is already false in my portal-ext.propertes file. I have seen lifeay database and found that this user is partially imported into database. This might cause the exception. I would like to know why liferay imported this user data only in user_ table and not in other table. Do I remove this data from user_ table and again import.

check the LDAP for the proper values in the appropriate fields. I think there is a field with date which contains some invalid date/time
please have a through inspection for all the LDAP fields and the respective values for the user.

I have checked all attributes in LDAP server and it is there apart from that which date field you are talking about?
