r2752: Fix the paranoia-check to ensure the ldap-attribute and the
smb.conf-parameter for samba's "algorithmic rid base" in ldapsam are
identical.

It tried to get the value of LDAP_ATTR_ALGORITHMIC_RID_BASE via
get_userattr_key2string() for a very long time now. This just can not
work because LDAP_ATTR_ALGORITHMIC_RID_BASE is neither in attrib_map_v22
nor in attrib_map_v30. Instead, get it directly from dominfo_attr_list.

Ldapsam will now correctly refuse to initialize when admins tried
manually to have differing values for "algorithmic rid base" in ldap and
smb.conf. idmap_ldap is another story...
