Whitespace in Solaris 10 LDAP configuration

Spaces are allowed in the ldapclient command line if attribute is surrounded by "", i.e.
-a "proxyDN=cn=admin,cn=emea users,dc=example,dc=com"
or
-a "defaultServerList=123.123.123.1 123.123.123.2"

Failing to quote either attribute statement will cause the ldapclient command line to fail with a parsing error.

However, there are instances where quoting the attribute definition will cause the command line parsing to work and for the command to succeed but ldap lookups can still fail.
May 22 18:09:44 server1 nscd[4012]: [id 293258 user.error] libsldap: Status: 49 Mesg: openConnection: simple bind failed - Invalid credentials

The problem is resolved when the proxy user is replaced with another from an OU which doesn't contain a space, i.e.
-a "proxyDN=cn=admin,cn=users,dc=example,dc=com"
