I need to look into it. 
Right now , I don't have any idea to get both working together. 
Form the stack trace , it looks like smbd invokes getpwnam syscall which loads gsaldap library , based on the entry in /etc/methods.cfg. And returns something which the smbd can't handle.

That worked!  Only problem now  AFS login is broken.    We do you AFS to log into the server.  Any thoughts on how to get both working together.

Are you using GSA authentication ? 
If not, then you can comment out the below lines in /etc/methods.cfg and then try starting smbd
#GSA:
# program = /usr/lib/security/GSA
# program_64 = /usr/lib/security/GSA64

Ayappan,
I am having Todd Desantis who is on the openAFS team look into it as well.  I can live without AFS id I need to.  Just will have to have a local id and password to keep track of.  I will let you know if Todd finds anything.
Thank you so much for all of your help!!

Ayappan,
I accidentally used  hash marks to comment out the GSA stanza in /etc/methods.cfg.   Todd noticed that and corrected it. With GSA commented out correctly, Samba and AFS  are working happily together now.
