Hi,
I followed your suggestions, I have set 'UseDNS no' in sshd_config and restarted sshd.
I tried 'getent passwd' and 'getent group' there is no delay in the output of these commands.
I tried to create home directory after login using pam_mkhomedir.so but failed.
I am getting delay only while login. I am getting below errors during login. Please see the below error and kindly help me to fix this delay problem.

Thanks and Regards,
