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.

ypinit

YPINIT(8)						    BSD System Manager's Manual 						 YPINIT(8)

NAME

     ypinit -- initialize NIS subsystem

SYNOPSIS

     ypinit -c [domainname] [-l server1,...,serverN]
     ypinit -m [domainname] [-l server1,...,serverN]
     ypinit -s master_server [domainname] [-l server1,...,serverN]

DESCRIPTION

     ypinit initializes the files and directories that are required for a NIS client or server.

     If domainname isn't specified, the default domain (as returned by domainname(1)) is used.

     The following options are available:

     -c      Create a NIS client.  Initializes /var/yp/binding/<domain>.ypservers to contain a list of ypservers for ypbind(8) to connect to.

     -l server1,...,serverN
	     Set the list of client servers from the command line rather than prompting for them interactively.  The format is a comma separated
	     list of server names with no spaces.

     -m      Create a master NIS server.  Generates map data from local files (/etc/master.passwd, /etc/group, etc.).

     -s master_server
	     Create a slave server.  Downloads the maps from master_server, which should be the active master NIS server.

     To rebuild or refresh the maps for the NIS domain <domain>, change to the /var/yp/<domain> directory and run make.

FILES

     /var/yp		 master NIS directory; contains the template makefiles.
     /var/yp/<domain>	 directory to store NIS maps for <domain>.
     /var/yp/binding/<domain>.ypservers
			 list of NIS servers to bind to.
