[Samba] Urgent: LDAP showstopper

[Shekhar]

I have a Smaba2.2.5+LDAP Setup
Many of my newly added users suddenly not able login even I am not able to
add any new users.
When I run smbpasswd -D 99 e91255 e91255 it gives the foll o/p.
This has beame network show-stopper and the users are started complaining.

TIA
Shekhar
