It is pointing unidirectional quotes may be the mail format changed it , its OU="Service Accounts".

The above uses directional double quotes (U+201C and U+201D) rather than the normal non-directional double quote (U+0022). This might just be because your email client is trying to make things pretty, but it's worth checking that the same isn't in your guacamole.properties. I don't think the directional quotes will have the same meaning to software expecting double-quoted values, including LDAP servers. Also, I don't think Guacamole requires that you quote spaces in the configuration file, which is, I assume, why the quotes are in there. My configuration that uses LDAP has a space in the OU, and I don't have any trouble with the space and don't use quotes. -Nick "This e-mail and any attachments to it (the "Communication") is, unless otherwise stated, confidential, may contain copyright material and is for the use only of the intended recipient.
