Old 03-22-2019
Although i am sure Corona688s suggestion is working fine for reasons of maintainability and understandability my suggestion is to use arrays for this kind of data. If the number of paramter sets to cycle through increases it is easier to extend this way. Something like this:

Code:
BASE=/opt/SP/
server[1]="server1" ;    user[1]="user1"  ;     dom[1]="dom1"
server[2]="server2" ;    user[2]="user2"  ;     dom[2]="dom2"
server[3]="server3" ;    user[3]="user3"  ;     dom[3]="dom3"

(( i = 1 ))
while [ $i -le ${#server[@]} ] ; do
        ssh -t "${user[$i]}@${server[$i]}" "cd $BASE/${dom[$i]} ; exec bash"
        (( i += 1 ))
done

I hope this helps.

locktest

LOCKTEST(1)							  [FIXME: manual]						       LOCKTEST(1)

NAME

       locktest - Find differences in locking between two SMB servers

SYNOPSIS

       locktest {//server1/share1} {//server2/share2} [-U user%pass] [-U user%pass] [-s seed] [-o numops] [-a] [-O] [-E] [-Z] [-R range] [-B base]
		[-M min]

DESCRIPTION

       locktest is a utility for detecting differences in behaviour in locking between SMB servers. It will run a random set of locking operations
       against //server1/share1 and then the same random set against //server2/share2 and display the differences in the responses it gets.

       This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers.

OPTIONS

       -U user%pass
	   Specify the user and password to use when logging on on the shares. This parameter can be specified twice (once for the first server,
	   once for the second).

       -s seed
	   Seed the random number generator with the specified value.

       -o numops
	   Set the number of operations to perform.

       -a
	   Print the operations that are performed.

       -A
	   Backtrack to find minimal number of operations required to make the response to a certain call differ.

       -O
	   Enable oplocks.

       -u
	   Hide unlock fails.

       -E
	   enable exact error code checking

       -Z
	   enable the zero/zero lock

       -R range
	   set lock range

       -B base
	   set lock base

       -M min
	   set min lock length

       -k
	   Use kerberos

       This man page is correct for version 4.0 of the Samba suite.
