[Samba] samba segfault with autofs schema

[Steve Thompson]

Samba 4.0.0beta3, CentOS 6.2 32-bit.

I am loading the automount schema into a vanilla Samba4 database. The 
schema can be found at:

 	http://http://www.cbe.cornell.edu/~smt/Automount_template.txt

and I am loading the schema as follows (samba is shut down):

 	ldbadd -H private/sam.ldb.d/CN=SCHEMA,CN=CONFIGURATION, \
 		DC=DOMAIN,DC=TEST,DC=CORNELL,DC=EDU.ldb Automount_template.txt

This appears to work without any issues. When starting samba with the 
automount schema loaded (no entities are using the schema, yet), it now 
segfaults at start. Without the automount schema loaded, it runs OK.
