Hi, We were able to resolve the issue by deleting the "locks/gencache.tdb" file.
On deleting the gencache.tdb , the SID reverted to the correct username, the "force user". Hope this is useful to anyone with the issue.

We have samba version 3.5.8 installed. Our samba configuration was working fine but all of a sudden in a random manner, we see user "sids" appearing instead of username in the security section of file properties for few of the shared resources. On googling I did come across the issue but no satisfactory solution/explanation. Also the "same samba configuration" had been working fine for years. We use the "force user" in smb.conf and would expect the username of the "force user" to appear instead of the SID. Here is the relevant slice of the smb.conf [shared_folder] writable = yes browsable = no path = /opt/software/shared/st0007/samba force user = st0007 valid users = domain1+winowslogin domain1+windowslogin2 st0007 read list = wherein , we would like folders in the "/opt/software/shared/st0007/samba" to be created with user st0007 when created via samba. The user st0007 is a valid unix user. What we find is that when folder is created in the shared resource(shared_folder) by someone in the valid user list, the folder seems to have SID ( which maps to correct uid on using wbinfo ) shown instead of the username. The group mapping is fine ( as seen in /etc/passwd for the user). As a consequence of the user being different from the force-user which we would like it to be, the folder cannot be renamed, cannot be deleted via samba by the valid user. The folder owner is st0007 when seen in the unix environment. And this behaviour is now random. It works for some shared user (i.e , we get force username on the securities tab). Could this issue be due to "changes" in windows controller etc as the problem had seemed to have gone away once on its own, ie the SIDs reverted back to the username. But now it seems to persist. Here is the chunk of the global smb.conf file as well...
