What value is in the LDAP attribute, with our without the pending 'S'?

http://wiki2.dovecot.org/Quota/Configuration says:
"All of these support also b/k/M/G/T/% suffixes." (No "S" here.) and:

"Backend-specific configuration currently is used only with Maildir++ 
quota backend. It means you can have the quota in Maildir++ format (e.g. 
"10000000S")." Which I interprete as: If the quote is read from Maildir 
storage.

You read the quota from LDAP, hence, the 2nd statement does not apply.

If you have a "S" suffix in LDAP, remove it.

You could patch Dovecot to accept the "S" suffix like "B", see 
src/plugins/quota/quota-util.c in function quota_limit_parse().

Maybe, ask the Dovecot development team for an enhancement.
