I hve done this in SOAP api..but not in CLI..qucik output from "zmprov ca" says:
[zimbra@zimbra1 ~]$ zmprov ca
usage: createAccount(ca) {name@domain} {password} [attr1 value1 [attr2 value2.. .]]
zmprov [args] [cmd] [cmd-args ...]
-h/--help display usage
-f/--file use file as input stream
-s/--server {host}[:{port}] server hostname and optional port
-l/--ldap provision via LDAP instead of SOAP
-L/--logpropertyfile log4j property file, valid only with -l
-a/--account {name} account name to auth as
-p/--password {pass} password for account
-P/--passfile {file} read password from file
-z/--zadmin use zimbra admin name/password from
so may be you want to use he server switch and see if the user gets created on that server.
something like:
zmprov ca name@domain.com password -s host: port
*
host: port there is NO space after colon..i just did so it dont show up as smily :P
