samba - Nov 2006 - Net use statements hanging at execution after upgrading to 3.0.23c

I just recently upgraded my Samba server from 3.0.20b to 3.0.23c and my 
'net use' statements are hanging at execution from a Windows
workstation.
 My Samba server is running on AIX(5.2 ML 9) with an ldap backend(Tivoli 
Directory Server 6.0).   I compiled Samba with the latest OPENLDAP 
libraries on my AIX platform using steps below: 

1) compile for openldap libraries

./configure --prefix=/opt/openldap --enable-slapd=no
make depend
make
make install

2)
export CPPFLAGS="-I/opt/openldap/include"
export LD_LIBRARY_PATH=/opt/openldap/lib:/usr/lib
export LDFLAGS="-L/opt/openldap/lib"



3)configure for samba

./configure --prefix=/usr/local/samba \
--with-acl-support \
--without-winbind \
--with-ldap

make
make install


Did something change between these releases that would prevent me from 
doing mounting a share(net use)?
