Thanks for your timely reply.
We have verified the things which you have mentioned in your mail in the
security settings but with any combination the result does not change. We
have also resolved the invalid parameters and module load warnings that was
getting reported in the log file.
When we give net rpc join -U Username%password , its joining to the domain.
But when we give net ads join -U username%password , its giving problem and
reporting the following error
Failed to get ldap server info
ads_connect: No results returned
I had attached the log file (with ebug level set to 10) in the last mail
that was the output of
net ads join command
I am pasting the samba global setting here,
root preexec=/usr/local/arm/samba/bin/smb-preexec '%S' '%I' '%U'
root preexec close=Yes
root postexec=/usr/local/arm/samba/bin/smb-postexec '%S' '%I' '%U'
If any other group members can throw light on this issue it will be helpful.
