Now,
Some parts work. The security level AuthNoPriv and AuthPriv work but
noAuthNoPriv doesn't works because php doesn't accept null or '' to
auth_protocol and priv_protocol. I think this fix is simple the snmp v3
with noAuthNopriv is very similar of snmp v2c.
if I try:
snmp3_walk('192.168.130.124','test','noAuthNoPriv','MD5','','','','');
I have this error "error(snmp3_walk(): Could not generate key for
authentication pass phrase: MD5)"
if I try:
snmp3_walk('192.168.130.124','test','noAuthNoPriv',null,null,null,null,'');
or
snmp3_walk('192.168.130.124','test','noAuthNoPriv','',null,null,null,'');
I have this error "Invalid authenfication protocol:"

Description:
------------
I try to make a query with snmp v3 and I have an error: "snmp3_walk():
An error occurred" or "snmp3_walk(): No response from 192.168.130.124".
If I execute a query with net-snmp 5.4.1 the query is ok. If I execute
the similar query with php I have those errors.
Reproduce code:
---------------
AuthNoPriv
net-snmp Query:
snmpwalk -v 3 -l authNoPriv -a MD5 -A jesuisuntest -u test5
192.168.130.124
it Works!
Php snmp
snmp3_walk('192.168.130.124','test5','authNoPriv','MD5','jesuisuntest','','','');
Error !
noAuthNoPriv
net-snmp query:
snmpwalk -v 3 -l noAuthNoPriv -u test 192.168.130.124
it works!
PHP snmp
snmp3_walk('192.168.130.124','test','noAuthNoPriv','','','','','');
error(snmp3_walk(): Invalid authentication protocol)
if use the default
snmp3_walk('192.168.130.124','test','noAuthNoPriv','MD5','','','','');
error(snmp3_walk(): Could not generate key for authentication pass
phrase: MD5)
Expected result:
----------------
Similar return value than smnp v2c
Actual result:
--------------
all method make an error
